Hi,
I'm having trouble with our Windows NFS server, running Server 2008 R2 Enterprise with SP1 and all updates applied. Most of the time, the clients that have the NFS share mounted can access and browse the share fine. However, periodically when browsing to the NFS share, none of the directories or content in the root of the NFS share will be listed to the client. Doing an LS returns 0 total items. If you wait for a few hours and try again, it will typically work, or if you restart the NFS server service, it will work right away. Even when directories are not listed, they can still be browsed to, and subdirectories seem to list their contents just fine.
There is a hotfix that perfectly describes this issue, I have applied it as described and rebooted, but the issue still crops up occasionally. Is there anything else I should try?
