What could cause a server to have slow response to network requests?
Posted on 2011-09-19
I have a windows 2003 server that has a dual network card setup. We only work with one card and disable the second card. Last Wednesday we started to see very slow interaction with the server when trying to talk with remotely (I.E. Active Directory manager, DNS listing, DHCP listings and so on). Over the weekend I worked on the server and found that working with the above mentioned items when directly on the server were fast.
To test some things, I switched to the second network card and disabled the first card. I found the same results and interaction was still slow when working remotely but fast when on the system. The system is running all the current patches, drives, and no other software has been installed before the problem started.
This is the AD Master server and has been running for 5+ years.
What could be causing this problem?
