I need some assistance with a 2008r2 file server that becomes inaccessible periodically throughout the day.
some background on the issue...........
I have a standalone 2008r2 file server. server seems to run fine for a period of time and then suddenly stops accepting connections. this occurs randomly throughout the day. the only way to fix the problem is to restart the server.
one of the things I've noticed is that shares are inaccessible over the network but if I open the share from the server itself via the same UNC path, it works.
DNS checks out fine, network connectivity is fine, error logs do not give any info on the problem.
when checking sessions on the server, I noticed during one outage yesterday that the server had 1024 open files when it stopped working. the specificity of that number led me to believe that it was a limit of some sort, which led me to this article (http://support.microsoft.com/kb/324446/en-us
the registry entries in the article were applied, issue still persists.
when checking the open file count during todays outage, it was sitting at 479 open files so I'm not sure about the limit being the cause.
Server patch level is up to date as of 3 weeks ago, this also includes all hotfixes from article (http://support.microsoft.com/kb/2473205/en-us
) which is specific to file servers.
Server is running symantec antivirus (v12.1.1). I plan on stopping AV on the server for a while to test if this is the cause.
Any assistance with this issue will be greatly appreciated.
