Common Computer Problem Questions:
You can use MalwareBytes to scan for malware and one of the various Virus Protection software’s to scan your computer if you think if you have a virus or malware. If you aren’t sure which software is best, or aren’t sure how to get rid of stubborn viruses and trojans, you may want to get professional help. Viruses, malware and Trojans tend to dig deep in your computer and hid in there. You want to ensure your system is clean and running smoothly or else you risk losing data, losing functionality or passing the problem on.
Checking that all your wires are plugged in at the router and from the plug is one of the first things you should do – provided of course that you have access to them. Verify that the power cord is connected and that all the lights of the router and cable/DSL modem are on. This may seem like a ridiculous suggestion but you should never disregard the obvious. You’d be surprised at how your configuration can be perfect, and after a while of playing around with settings you realize that the network cable leading from the router to the cable modem has come undone slightly.
You will also want to check that your wireless network adapter is switched on. Some laptops come with a small blue or red button on the side while others require you to enable it from the operating system. In Windows, go to device manager and check that your wireless network adapter is enabled. If you have a PCMCIA or USB wireless adapter try removing it and then re-inserting it while Windows is running so it will re-detect it. The lights on the adapter give an indication of whether there is a problem. On some cards, orange is to signify that the PCMCIA card has power and the other is green to show if a connection has been established. A blinking green light means that you are not in range of a wireless access point or there is a problem with connectivity, whereas a stable light means a connection has been established successfully. Take a look at your device documentation as these sorts of details will vary with each product.
The first thing to do is verify that you have configured your e-mail client correctly.
At the very least, make sure that you have your |POP (Incoming) Mail Server| set to |/yourdomain.com/ |(where |/yourdomain.com/| is your actual domain name.) Do *not* prefix your domain name with |http://|, |www.|, |mail.|, |pop3.| or any other prefix.
Also verify that your username and password have been entered correctly. For the e-mail account |/[email protected]/|, the correct username is: |yourdomain| — it is *not* |yourdomain.com|.
Check your Domain Registration Status
If your domain name registration has expired, no functions associated with your domain name (e-mail, www, ftp, etc.) will work. Also, if the Domain Nameserver (DNS) information associated with your domain name is not pointing to tintagel.net nameservers, you will not be able to access any functions on our servers by domain name. You can use any WHOIS lookup to check the status of your domain name. We offer our own WHOIS lookup at http://www.nicforce.net/whois/.
Check Your Redirects, MailLists, Infobots, & PlusRoamer Configuration
The most common cause of e-mail delivery failures is an incorrectly configured default redirect in your e-mail forwarding. Log in to your Web Control Panel (http://www./yourdomain.com//cgi-bin/plusmail, where “/yourdomain.com/” is your actual domain name) and select the E-mail Forwarding link. The first redirect listed should look like this:
|default [email protected]|
The default entry must be your primary account login (|[email protected]|, where yourdomain.com is your actual domain name.) If you set your default redirect to a different e-mail address, your e-mail will not be delivered predictably or reliably. For example, we see a lot of entries like this:
|default [email protected]|
What you want is for all of your e-mail to be delivered to your AOL account. What you get is none of your e-mail being delivered anywhere. If you want your mail delivered to an e-mail account outside of our network, set up your redirects like this:
Also, note that the primary login is the only POP login that can be redirected. Another common problem occurs when you set up a POP login and a redirect for the same name. This can result in mail not being delivered. Make sure that you do not have the same name duplicated in your POP users and redirects.
Check your MailLists and Infobots (Autoresponders). You cannot have a maillist or an infobot with the same name as a POP user.
Relay Attempt Failed Error
You attempt to send mail, but receive an error message that looks like this:
|protocol smtp; server response 550; relay attempt failed|
This one’s usually easy to fix: Simply check and receive your mail before you try to send mail. In order to prevent our mail servers from being used for the transmission of SPAM (junk e-mail), we’ve configured our servers to require that no mail can be sent from a given domain’s SMTP (outgoing mail) server unless the same domain’s POP (incoming mail) server has been accessed prior to the send attempt.
At the present time, it is only necessary to have checked for new mail once during any 24 hour period. Checking the POP (incoming) mail server effectively “unlocks” the SMTP (outgoing) mail server and allows the relay to go through.
Port 25 (SMTP) Relay Blocking
Another common source of the relay error is due to your local ISP blocking relays to external SMTP servers (Port 25 Relays). ISPs do this to eliminate their network from being used to transmit spam — they simply do not allow anyone to connect to any SMTP server outside of their network. Almost all of the larger ISPS (notably, Earthlink and MSN) and more and more smaller ISPs are now blocking Port 25 Relays.
The solution to this problem is to simply substitute your ISP’s SMTP server information for your domain name in your e-mail client configuration. We recommend this configuration even if your ISP is not blocking relays, as it will generally result in more reliable SMTP connections. Mail will still appear as coming from your domain (as long as you have your |From| and/or |Reply-to| addresses configured correctly.) Your ISP can provide the information you need to set up the connection — usually mail.myisp.net or smtp.myisp.net. Contact your local ISP’s support staff to obtain the correct settings.
SSL Negotiation Failed Errors
You may see an error referring to problems with SSL, similar to one of the following: SSL negotiation failed – negotiated key exchange length is -1
SSL negotiation failed. You have configured this personality/protocol to reject any exchange key lengths below 0. But the negotiated exchange key length is -1 Hence this established secure channel is unacceptable. Connection will be dropped. Cause (-6992).| Our mail servers do not currently support SSL connections. These errors indicate that your e-mail client is configured for this unsupported connection type. In Microsoft Outlook, uncheck the box next to |This server requires a secure connection (SSL)| in your Advanced properties section. If you’re using Eudora to check your mail, follow these steps:
1. Right click on your personality name to bring up the menu. Then, click “Properties”. 2. Look toward the bottom of the box until you see “Secure Sockets When Sending”. Change that option to “Never”. 3. Click on the “Incoming Mail” tab at the top of the box and change “Secure Sockets When Receiving” to “Never” also. 4. Click “OK” and check mail again. The error should not return.
Firewall and Anti-Virus Software
Improperly configured firewalls and/or anti-virus software can interfere with POP and SMTP connections. Both the Norton and PC-Cillin anti-virus software packages have proven to cause sporadic and unpredictable failures with POP3 connectivity.
Try temporarily disabling any software of this nature and see if the problem disappears. If it does, you’ve identified the source of the problem. You’ll need to contact your network adminstrator or the software manufacturer for assistance with proper configuration.
After disabling any virus protection software, double-check your e-mail client configuration . Many virus protection programs will overwrite your settings (for example, they may replace the POP Server name with |localhost| and the Username with something that looks like |yourdomain/yourdomain.com|.
You could receive any number of error messages describing unavailable server, connection with the server reset, server connection timed out, etc. In some cases you can receive mail without problem, but cannot send mail.
There are all sorts of conditions that can contribute to sendmail problems, including the standard internet connection issues, which can cause timeouts when connecting to your web site via browser, POP, FTP, or telnet.
Sending mail (via SMTP) and receiving mail (via POP) are related, but essentially independent, processes. The fact that you can receive mail, but not send mail, is not as inconsistent as you might imagine.
For example, when you send e-mail, the actual destination server of the mailto address is contacted and resolved before our server allows the mail to be sent. Problems with the destination server can result in timeouts and other errors.
This process also increases the number of “hops” the process encounters, as the transmission goes from your ISP to our servers to the destination server then back to our servers to be sent. The more hops, the greater the chance for a dead or slow node, the greater the chance for a timeout error.
Running a traceroute from your connection to your domain, and to the destination server might help pinpoint the source of the problem. If the problem is related to Internet congestion or problems with intermediate routers, it will usually disappear within a short time.
America Online (AOL) customers report more problems in this area than most other users. AOL was not originally conceived or designed as an Internet service provider and most of their system protocols are not standard Internet protocols. They seem to have consistent problems sending and receiving e-mail through their own system — trying to use an AOL connection to drive Internet protocols is even less reliable. According to the latest information, AOL does not support external POP/SMTP connections — they may work or they may not. The only solution to this problem is to switch to a “true” Internet Service Provider.
Reporting E-mail Problems
If the information above does not solve your e-mail problem, please provide enough information so that we can effectively troubleshoot the issue.
*IMPORTANT NOTE:* If you are unable to receive mail from your account, *provide an off-network e-mail address that we can reply to* — if the problem is not related to a server-side issue, and the only e-mail address you provide is on the affected domain, you won’t be able to receive our response to your problem report.
At the very least, we’ll need the following information:
1. Your domain name
2. Username(s) for the affected E-mail account(s)
3. Password(s) for the affected E-mail account(s)
4. A copy of the *exact* error message you’re receiving
5. A complete description of the problem and when it occurs (e.g., sending, receiving, or both?)
Other information that can be helpful includes:
1. The E-mail client you’re using (Outlook, Eudora, etc.)
2. The speed and type of your Internet connection
3. If you have access to a different ISP account, does the problem occur with that connection, too?
4. Is the problem consistent or sporadic?
5. When did the problem start?
6. The results of a traceroute to|mail.yourdomain.com|, where yourdomain.com is the name of your actual domain name
Some classic reasons a computer slows down.
1. It’s possible that your computer may have so many background programs running that there is not enough main memory to run your main programs. All the icons in your computer’s system tray are background programs using memory. ASK ERIK can help you fix this.
2. Your hard drive could be too full of data to function efficiently. There should be at least 2MB-3MBs (200,000 -300,000 bytes) of free space to allow for disk file chores. Note that this mostly applies to the C: drive or whatever drive your Window’s cache is on.
If your C: drive is too full, delete unused programs on the C: drive to make space.
3. Your computer could have a fragmented hard drive. This results from programs being loaded and deleted. Run the Window’s hard drive defragmenter (Defrag) once a month.
4. If you have 256 MB of memory or less, or you like to play games, you may not have enough system memory to run your software efficiently. You should probably upgrade to 1GB or more of system memory.
5. You could have old or conflicting Windows device drivers. An example would be you might actually have two entirely different video drivers on your system and Windows could actually be alternately using both of them. To prevent this problem, First boot the computer in Safe Mode by pressing and holding the F8 key during startup, after the DOS memory check has completed. While in Safe Mode select Start/Settings/Control Panel/System/Devices. Click on all the devices and see if the various drivers have any yellow or red exclamation marks (which indicates a driver conflict) and also determine if there are any duplicate drivers that can be eliminated.
You may have to delete and reload a driver to correct these problems. Duplicate drivers can and should be deleted.
6. As each new Windows program is installed and uninstalled, it leaves behind parts of itself that can slow down or crash your computer. These are mostly .dlls and other shared files.
It’s also very possible when uninstalling a program that needed Windows system files can be deleted. When your computer asks if you want to uninstall shared files it’s usually safest to say NO — even if your uninstall program claims the files are not being used.
