Server 2003 mapped drive disconnects from SAN

[Guest The_Nite_Owl]

We have a Windows 2003 SP2 server with mapped drives to another 2003 server

with SAN shared drives.

The mapped drives periodically disconnect from the shares and cannot be

reconnected without either rebooting the server then clicking the drive and

entering the credentials, or deleting the mappings then re-creating them and

entering the credentials.

 

The mappings in question are established using credentials other than those

of the current logon.

I know that Server 2003 SP1+ no longer caches credentials when you map using

a different user name.

 

I suspect that when the connection is first established and the credentials

passed, the SAN server is setting up some time limited session for that

connection and that once the time limit is exceeded the only way to

re-connect is to re-authenticate but since the application server cannot

cache the credentials this cannot happen.

Is there a setting on the SAN server that can either disable the time limit

or expand it further so the disconnects will happen less frequently? This

is not the 15 minute timeout for closing out an inactive connection, that

occurs also but the connection comes back as soon as it is accessed.

Any idea what the time limit on this connection might be?

 

Two of our production servers lose their connections to these drives a

couple times a week though I have not yet been able to predict when it might

happen. It brings down our print production system until someone can

disconnect and re-map the drives and this often happens in the wee hours of

the morning when our print activity is at it's highest point.

 

Other mapped drives to other servers do not have this problem, only the

drives to the SAN share space.
