Microsoft Exchange Server. HTTP 500 Internal Server Error.Any recommendations?


To resolve this problem, follow these steps on your Exchange 2000 or Exchange 2003 back-end server. Alternatively, follow these steps on another computer that has access to the same domain controller and the same global catalog server.

NoteThis procedure requires the Exchange Server Fix Toolbox
1.Start the the Exchange Server Fix Toolbox
  1. Right-clickYour_back-end_Exchange_server, and then clickProperties.
  2. Clicknetworkaddressin theAttributeslist, and then clickEdit.
  3. Add a new value forncacn_ip_tcp. Use the FQDN of the server instead of the NetBIOS name or the host name of the server.

    The syntax for this value isncacn_ip_tcp:FQDN. For example, if your Exchange back-end server has a host name of EXCHANGE1 and the FQDN is EXCHANGE1.domain.com, use the following value forncacn_ip_tcp:ncacn_ip_tcp:EXCHANGE1.domain.com
  4. Remove the oldncacn_ip_tcpvalue that contains the NetBIOS name or the host name of the back-end server.
  5. Apply this change.
  6. Because your Exchange computer may change this value back during a failover or a system attendant restart, configure the following registry value on both nodes of the cluster:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters\UpdateProtocols
  1. Right-clickUpdateProtocols, clickModify, type0in theValue databox, and then clickOK.
  2. If your network uses a Hosts file on the back-end cluster node, modify it by using the following order of entry:
  3. Restart the Exchange services on the back-end cluster node.
  4. If there are multiple domain controllers, wait for replication to occur before you try to log on from the front-end server. If the problem is not resolved after replication is complete, restart the IIS Admin Service on the front-end server.
You can obtain the Exchange Server Fix Toolbox by visiting the following site: https://www.fixtoolbox.com/exchangeserverfix.html

New refilled cartridges do not work


I am with Inkjet411 (i.e. technical support for Costco's ink refill machines). It would be helpful to know which cartridges we are talking about. For any of the severe HP 60 / 61 / 901 / 74-75 / 93-97 ink cartridge error messages which result in 'no printing' (i.e. Incompatible Print Cartridges / Cartridges Error', etc.), in most cases the cartridge is electrically damaged (they don't make them the way they used to). Our test lab has run numerous studies across 100+ printer models. I suggest you run the Tap 41 diagnostic 'print-mech tap test' to check the cartridges electrical health first (see www.inkjet411.com for specific printer models instructions or ping youtube for our videos on this). Here is just one example for the HP 74-75 ink cartridges in the HP Photosmart C4200-C5500 series printer models:
https://www.youtube.com/watch?v=8fE-IM4AVMc

>> I also suggest you watch this informational video which explains the issue in more detail:


https://www.youtube.com/watch?v=BskAfa6NJSg

>> Now, it is possible to force the printer spit out a print job during these error conditions (however, usually just one print job at a time) with a marginally performing ink cartridge by clearing the checksum code, but this is only a temporary solution (i.e. on the HP Officejet J4xxx and 4500 series for example, press * + # keys together, then press 123. Go to Information Menu, then go to Checksum for Relock data, a 4/5 digit code will be displayed...then go ahead and press Cancel to exit out. Send your print job thru. We have many of the 'access' procedures for hundreds of HP printer models on Inkjet411.com. Good luck!

How to Fix Gmail Temporary Error 500: Gmail Access Problem?

In web world, the Gmail Error 500 truly indicates an Internal Server Error message and occurs while the server encounters an unexpected condition to prevent it from fulfilling the request. The issue is not only confined to the Gmail accounts. According to Outlook technical support professionals, one can check this by simply logging into a friend's account from the same computer.The issue is further not limited to the computer or network itself but yes one can easily perform a check by trying to log in from a different computer or even from a network.
Steps to fix the Gmail Temporary Error 500
Step1: Browser Cache Issues
Generally clearing our browser's cache as well as cookies can easily fix out most of the issues a user is facing with the Gmail account. Therefore the first attempt to resolving a Gmail Login issue should be that of clearing out cache files of the web browser. If a user is using the Firefox, Google Chrome or even the Internet Explorer a user can clear cache by pressing the Ctrl+Shift+Del button.
Step2: Conflicting Browser Extension/Toolbars
An improperly coded browser extension which users may have recently installed could be the main cause of it which is stopping users from accessing a Gmail account. One can easily check this out by working with the browser in the "Safe Mode" section. If a user is using the safe mode then, simply click on the "Firefox Menu > Help > Restart" button with the Addons Disabled.
Step3: Internet Security applications such as Firewall, Antivirus
Ensure that the internet security applications such as Firewall, Antivirus are not at all interfering with the Gmail account. Different antivirus software that may have different settings for the internet usage, but as a general rule, one can surely check the following settings as described below by Outlook tech support team of experts:
