I have a problem: It all started when the IT services removed an old server from the net. Whenever one tries to open a simple text file or anything or right click some file or folder on whatever drive as e.g. C: or even the USB stick it takes more than 20 seconds till that action happens. Using a network protocol analyzer I found out that after the mouse event there are sent a number of name request via DNS and NetBios regarding that old server. When all of them returned an error after 20 seconds the chosen action is finally executed.
When I switch off NetBios over TCP/IP then opening files works without delay as it should. But this is probably not a clean solution since something in the background will still ask for the old server.
How can I find the application or service which is initiating the name requests so that I can change its settings?
I looked already for network drives but all the drives I can find are working correctly. It is also strange that the name requests are send no matter what file on what drive I try to access.
Since a lot of computers in our office have this problem and our IT services left us alone with this saying they can't find any problem, I would appreciate your help.
Thanks a million in advance!
