Have had Exchange server 2007 up and running for about 2 months. Recently I put new Domain Controllers up and demoted the the old ones. In addition to being DC's, 1 was a WINS server. About this same time it started taking a very long time to open the EMC and EMS for exchange 2007 (upwards of 2 minutes). Finally you will recieve a "end snap in" error, however if you press cancel, you can do what you need to do.
By searching around, I have already tried lowering the amount of users that are "preloaded" upon opening, however this did not help...additionally we only have 300 objects.
The reason I believe it is WINS is because we ran into this error when we first started setting up exchange is a test environment. We found that by turning on the "enable netbios over tcp/ip" within the network adapters settings that this problem stopped. However now that I have brought down the old WINS, and now even brought up a new WINS and pointed this to the correct IP, this is still happening.
I would like to phase netbios/wins out all together, however it seems as though some things are still relying on it. I have also looked at the binding settings for the network cards and NETBIOS is not even listed as a protocol to place lower in the chain....
