FMSA9 Losing Port 5353

[stanley]

Hi All

I posted this on TechNet, but want to try you guys as well.

We have a very busy production server running FMSA9 on Windows Server 2003 (yeah, go tell it to our IT department) and twice this week users have lost the ability to acquire the server. What we see is this:

Users with no files open on the server cannot see the server.

Users with any file open on the server can see all the files on the server.

Users with any file open on the server can work as normal.

Admin can run the console remotely (but a bit slow).

Admin can RDC into the server normally.

Rebooting the server solves the problem, but this is happening during the middle of the day, with most users unaffected, so that's not a great solution.

Has anyone seen this before? I have a vague recollection of having a similar problem years ago, but can't recall if that was on 5.5 or 7 or what. Any hints appreciated.

Thanks

Stanley

Hey Stanley, good to see you back.

Did you try installing another version of server on another box? I would do that to see if perhaps the issue is on your current server or the network possibly. Did you check any soft firewall updates? Also you may want to put in a new copy of your server.pem file on the server.

Oh also, since you are on FMS9 dont forget about this if you are using SSL. Upgrade if you haven't already.

I have a second server running on the same switch, which does not have the same problem. When this has occurred (it's only been twice so far) I have not had the same issue with the second server. However, I have not really compared their configurations too closely.

Thanks for the SSL thing - yes, we are using SSL!
