I have 6 DFS servers – 2 each in 3 locations. Each server has 4 DFSRoots. The configuration started on a Windows2008 Std virtual Hyper-V server. Currently the servers are at Windows2008 SP2 Std.
About a month ago I upgraded the OS on one server to Windows2008 R2 SP1 Std. This server (Server2) is marked as the “last among equals”. As such users rarely connect to it. Shortly after this when the “first among equals” server (Server1) was down for maintenance, we noticed a pronounced delay (90+ seconds) when users were connected to Server2 and trying to open Excel& Word documents, but not for WordPerfect (yes we still use this) and PDF documents.
In researching this I found the article “How to configure DFS to use fully qualified domain names in referrals” at http://technet.microsoft.com/en-US/library/cc732006(d=printer).aspx which would be helpful, no doubt. Preparing to make this change I noticed the problem server - Server2 the W08R2SP1 server - returned a Site name of “No Site Association” when running:
Dfsutil /Root \\<DomainName>\<ShareName> against all four DFS share names.
Even though the DFS GUI shows the proper site information. Also the other 5 servers all show the correct site info for Server2.
So I found an article suggesting running:
dfsutil /RemFtRoot /Server:<TargetServer> /Share:<TargetShare> &
dfsutil /addFtRoot /Server:<TargetServer> /Share:<TargetShare>
would correct this. The remove completed successfully. The “add” failed with the message “Could not execute the command successfully. SYSTEM ERROR - Cannot complete this function.”
In the end I had to use the DFS GUI to add the server back into the system and the site info still indicates: “No site association”. Any suggestions as to how I can fix the Site situation?
Thanks!
