Second Shared Design Library folder

I'm loathe to post this in the "General" thread...but I don't see a better place at the moment...

We have a secondary Design Library folder (called Catalog_Components) served by an XP Pro box on our network. Basically contains...well...what it says. We do have this folder defined as a Shared Library within PDMW also.

So far...so good.

Whenever I pull the Design Library tab open within Solidworks, I get a message saying that folder doesn't exist and wants to know if I wish to remove the nonexistent folder from the design library file location reference.

The problem is - I can say "No" to the dialog box and continue browsing through the sub-folders - grabbing parts as I wish - even though according to SW, the folder doesn't exist.  I have no issues browsing the share manually in Explorer or through regular window navigations.

I understand - this is likely a network connectivity issue (I've tried using straight IP address info etc with no affect) but I'm wondering if anyone's seen this before.  The fact that I have issues only in Design Library makes we wonder if there isn't something going on with the design library file location reference functionality though.
