We are having a very odd issue with our windows 2003 server. This server hosts several sql databases. Starting Friday, users started to have issues connecting to the server. They could be in the middle of entering orders in a sql based application and all of the sudden, they get an error about the sql server not being found. A few other things, if the user tries to ping the server by IP, they get timeouts - almost as if the server shutdown. To make things even more odd, a person sitting in the next cubicle is still able to ping that server just fine and access their sql applications. This issue seems to be affecting most people but you would think it would affect them all at the same time. It doesn't. We have no firewalls running on this server and the firewalls have been shut off on the workstations. We've also updated the network driver on the server and verified that the switch isn't having issues. At first glance, you would just chalk it up as a network issue with the server, however considering that the users aren't experiencing the problem all at the same time makes things very odd. Some users experience the issue multiple times an hour and others aren't having the problem at all. Any help would be greatly appreciated. Also, another interesting issue is that when this issue occurs, the end user is still able to hit other servers on the network - and if I go to the server and try to access that end user's workstation, I cannot. It almost seems like a denial of service attack.
