I have a 4 server Farm, 1DB, 1 App and 2 WFE's
I've noticed that if I am on WFE1 and I go onto a site and try to add someone to a Permissions Group all is fine. As soon as you start typing the users name in it starts to appear and resolves as you would expect.
However, on WFE2 and APP Server, the same name being added to the same permissions group does not resolve. Also, as I type no names start to appear.
Also, if I use the same account but not on a server I cannot administer Permissions as the names do not resolve.
Frankly, I'm stumped. It's the same process on the same server farm. Something must have gone wrong during the setup but I'm at a loss to know what.
Anyone with any advice on where to start with this one would be most appreciated. Thanks. Dan
