I'm not sure I can comment on the opportunistic locking (I may have missed that thread), but Sysvol, which holds Netlogon, uses FRS to replicate. The only time I know of where this isn't true is if you've got 2008+ and have specifically made some changes to use DFSR.
I can tell you that we have our msi files on DFSR volumes and have not had trouble with failed installations due to opportunistic locking issues. Prior to DFSR, we used to have them on a separate DFS (FRS) volume and that also worked (waaaay back to Win2k server SP1). We've never installed our MSIs from netlogon. From: Ralph Smith [mailto:[email protected]] Sent: Tuesday, February 16, 2010 10:46 AM To: NT System Admin Issues Subject: Windows Installer, opportunistic locking and the Netlogon share I recently had a problem in which applications assigned through group policy were not installing on some computers, which turned out to be a combination of the fact that I stored the apps in the NETLOGON share, and also had disabled opportunistic locking on the failing computers. This is in a Windows XP SP3, Windows Server 2003 SP2 environment. My question is: When I finish upgrading all of our locations to Windows 2008 R2, with still almost all XP SP3 clients, will I run into a similar problem if I put the application's .msi files in a DFSR share as I had with the 2003 NETLOGON share? I'm not sure what is unique about the NETLOGON share that causes this problem, and wondering if it has to do with being part of a DFS with replication share also. Thanks for any insight.
