Interim Roaming Profile Writes?

WIndows 2008 R2In the Citrix Optimization Guide: User Logon, there are two lines which seem a bit cryptic:

With Windows Server 2008 R2 Active Directory, enable interim roaming profile writes.  Alternatively, use a third-party profile solution that manages multiple sessions more appropriately.

“With Windows Server 2008 R2 Active Directory, enable interim roaming profile writes.”

I can’t find a reference to interim roaming profile writes.  The closest setting I can find with Windows 2008 R2 is the Group Policy setting Background upload of a roaming user profile’s registry file while user is logged on.  According to Microsoft’s Ned Pyle, Folder Redirection should take care of the rest of the profile data, which you should be storing in known folders.

So this is the likely setting Citrix is referring to.

“Alternatively, use a third-party profile solution that manages multiple sessions more appropriately.”

In the case of Citrix, they are probably referring to the Active Write Back feature of their Profile Management tool.  With Active Write Back “Changes are copied back to the network profile when updated files are closed, subject to no further updates in a window of 10 seconds after the close“.
