Are there any tools for DFS troubleshooting? Some searches suggest network monitoring, but if you dont know how to read the scans with DFS in mind it seems a bit pointless.
Looks like you have some inactive root server or link.
Use dfsutil.exe with /pktinfo switch to list down details of DFS root and verify all root and link servers are online.
some good articles on DFS
Youve got the tool Distributed File System under Start -> programs -> Administrative Tools. If you dont have it (for example on Windows XP) you can download the administration tool pack from microsoft: http://www.microsoft.com/downloadS/details.aspx?FamilyID=c16ae515-c8f4-47ef-a1e4-a8dcbacff8e3&displaylang=en
With the tool you can at least check the status (is the server and share online).
Please clearify what exactly you want to monitor or troubleshoot. Are you experiencing some dfs related issues? There are a few key points to check:
- DNS (is the forward/reverse lookup for the used dc's,servers and clients correct)
- Does a firewall block port 445 (tcp) or some other AD related ports?
- Are the file permissions on the DFS root set correctly? (a directory on the dc is created for every target you define)
After quite a lot of investigation it turned out the problem was "Pismo File Mount Audit Package" version 51.
Removing this fixed the problem!
Using Safe Mode+Networking identified this - although this kind of fix is getting harder and harder to do. Note to dev, use the error logging facilities!
