When running Design Manager on a peer-to-peer network with all Windows Vista machines the host will lock out the other computers when running the software

Modified on: 2018-01-03 17:18:09 -0500


This appears to be a problem with the new SMB2 protocol developed for Windows Vista. 

This problem actually will occur when sharing any file (not just a database) between two Vista computers.

Disabling SMB2 on the machine that hosts the share seems to solve the problem. Share works fine when a Windows XP machine hosts the shared folder because XP does not support SMB2 and the machines connecting will use SMB.

Two options are available:

Fix #1:  

This is a Microsoft Hotfix, you must call Microsoft and charges may apply. 

Fix #2: Apply this change at your own risk!

So far this is an undocumented problem only known by Microsoft's internal support staff, so use this information at your own risk. It is unknown if disabling SMB2 will have any other side-effects. To disable SMB2 on the machine hosting the shared folder, add a registry value named SMB2 under HKEY_LOCAL_MACHINE/SYSTEM/CONTROLSET/SERVICES/LANMANSERVER/PARAMETERS and set it to 0. Reboot.

We are recommending that our clients set up an XP machine to host the share until the problem is addressed in a real MS Knowledgebase article with proven results or until a fix is provided in a normal Microsoft Service Pack.

Below is a copy of the final response from MS Technical Support to Design Manager concerning the issue:
