Here's an annoying little glitch in Windows networking, courtesy of those mavens of SCREWING THE HELL OUT OF YOUR WINDOWS - Symantec/Norton.
I first encountered a problem after creating a VPN between two Windows machines (using the awesome LogMeIn Hamachi) but the problem is independent of VPNs.
You are logged into a Windows network. You can see shared folders on another machine but when you try to open one, you get an error message that includes the line,
“Not enough server storage is available to process this command.”
Typically, the full error message will be something like,
"\\XXXXXX is not accessible. You might not have permission to use this network resource. Contact the adminsitrator of this server to find out if you have access.
Not enough server storage is available to process this command."
where XXXXXX is the full network pathname of the resource (folder, for example) you are trying to open.
The problem is caused by a range of Symantec/Norton products and is on the server (the computer on which the shared folder sits) not on the client machine that is getting the error shown above.
The problem can be confirmed by checking the EventViewer on the server.
There is a simple guide to fixing the problem here.
You can read a bunch more by Googling the error message.
