Bluescreen when saving to Shares with symbolic links (wide links) on a NetApp with Kaspersky installed

 

Phew, what a title!

 

Had a customer recently who I was working with on doing a Netware –> NetApp CIFS migration utilising the Quest NDS tools.

 

All was working fine until one unlucky user attempted a save to a “Volume” share, they received a BSOD (repeatedly if they attempted again).

 

Now, to explain the NetApp CIFS configuration a little before ploughing on;

 

There are three shares created on the new NetApp;

SHARE1
SHARE2
VOL1

VOL1 contains symbolic links (wide links) to SHARE1 and SHARE2 to allow historic applications looking for \\SERVER\VOL1\SHARE1\FILE1.EXT to function.

 

The customer was also mid-AV upgrade – from McAfee to Kaspersky.

 

When a Kaspersky-running client attempted to save (via Office for example) they received a BSOD with the header RDR_FILE_SYSTEM (27). A Bug check analysis didn’t give me any more info (aside from an “Access Violation” error further down).

 

Testing was done with different XP SP/Office levels before we turned to the AV – and sure enough it looked to be Kaspersky.

 

Kaspersky replied to the support email sent very promptly – outlining this was a known bug in XP/2003 but Microsoft had only released a patch for Server 2003. However they had their own patch – which seemed to resolve the issue. I believe it to be a private release patch at the moment – however they have said it will be written into the next point release

 

Hope that helps someone anyway
