Network Shares Slow Opening
users are expericing intermittent slowness of their network drives opening and saving to their network drives. We have DFS replication running to which we think may be causing the issue. Below are some example warnings seen in the DFS replication event viewer:
--------------------------
The DFS Replication service detected that the staging space usage is above the staging quota for the replicated folder at local path D:\Users. The service might fail to replicate some large files and the replicated folder might get out of sync. The service will attempt to clean up staging space automatically.
Additional Information:
Staging Folder: D:\Users\DfsrPrivate\Stagi
Configured Size: 4096 MB
Space in Use: 4308 MB
High Watermark: 90%
Low Watermark: 60%
Replicated Folder Name: Users
Replicated Folder ID: 5B75CE09-E5ED-499E-9B9F-17
Replication Group Name: wshgroup.local\main\users
Replication Group ID: EC92CC8A-6CCA-45B0-926E-78
Member ID: A9864546-1E1D-4198-A1C6-F7
--------------------------
The DFS Replication service has been repeatedly prevented from replicating a file due to consistent sharing violations encountered on the file. The service failed to stage a file for replication due to a sharing violation.
Additional Information:

It appears to be affecting mainly and users with Windows 7. A few with XP machines have been affected to.
We have disabled the Windows Search Service and diabled the following:
netsh interface tcp set global autotuninglevel=disabled
netsh interface tcp set global rss=disabled
but still experiencing intermittent hanging of network shares

on our Win 7 systems we also use this for our mixed server network 2003/2008R2, if you disable Autotune, you need to do Heuristics too:
please test these options, we have used them with success with our Win 7 systems to fix all network/speed issues.
disable Remote Diff. Compression:
go to Programs & Features, click Turn Windows Features on/off and un-tick the option
disable Autotune:
netsh interface tcp set global autotuninglevel=disable
disable Scaling Heuristics:
netsh int tcp set heuristics disabled
enable Compound TCP
netsh int tcp set global congestionprovider=ctcp
we found those settings, along with disabling IPv6 on network adapters helped a lot. the last setting is off by default and only on with Server 2008. make sure your Win 7 systems have a good DNS link to all your DC's, as it relies on DNS a lot.
Network & Sharing Centre, go to Change Adv. Sharing settings and for Domain and Home profiles (incase they remote in from Home via VPN), scroll down to File Sharing Connections, and change the encryption mode to 40 or 56bit from the default 128bit which again works for Win 7 when connecting to non-Win7 or 2008 servers. SMB may also play a role, as SMB2 is used by 7/2008 but not by XP/2003.
