When users are connecting to our file server for their home drives and department shares they are getting poor performance when they attempt to sort either by date or name etc. The green bar moves along the top of the explorer window and it takes around 30 seconds for the folder to sort.
The file server is running Server 2008. I have kind of ruled out windows indexing. The issue is there if I disable the windows search service and also the performance bad if I map to the C drive on the file server which is not indexed.
It is specific to the file server as if I map to any drives on any other servers they work fine.
There is no performance issue on the file server. If I RDP onto the server itself and test sorting the folders they work fine it is only when you connect to them over the network. I am thinking there could be a DNS or DFS issue here because, interestingly if you map to the shares on the file server using the servers IP address they work fine. It is only when you map to them using the servers name that the problem occurs.
The issue does happen on the file server however if you map its own drives as network drives effectively looping back to itself.
The only difference I can see here is that the when the name is used the client machines have to talk to the DNS server first to rsolve the name to IP???
Can anyone offer any advice here?
