Hi

it seems like a issue with ServerA's networking. What does event viewer show for the time it stopped working?

Have you checked for Network card firmware updates or driver updates?

Hello,

No any suspected errors in event viewers.
Also I didn't try for network driver updates.

One more thing I forgot to tell you - Every time when i reboot server I need to disable/enable NIC to become this server in network.

Any how can i revert back the windows update done recently on server?

You can uninstall Windows updates via the control panel. Check the show updates box.

Look in your logs to find out what updates were applied most recently.

Hello,

In event logs,I have got following errors for .net =
--------------------------------------------
Unable to get the private bytes memory limit for the W3WP process. The ASP.NET cache will be unable to limit its memory use, which may lead to a process restart. Error: 0x80070005
----------------------------------------------
Could not load all ISAPI filters for site/service. Therefore startup aborted.
------------------------------------------------

Rest are WARNINGS.As per the scenario told by me...what if I remove only .net updates from control panel? Will that work?
