I have a user where he has a desktop and A laptop. Both are using Windows 7 Pro. Both the Desktop and Laptop have the My Documents mapped to a Windows 2003 R2 share. The desktop has its offline files disabled and just always talks to the server. Howerver alot of times when he goes to sync his laptop he gets "The file is in use by another process" even if his desktop is off. and just on the last couple of files that he worked on. If we wait for like an hour or longer then hit sync again on the laptop it will work fine on the files that it could not sync before. I know that eveyone points to op locking when this error comes up but it works on all the files fine it just breaks on the last couple of ones he touched. And if we just wait and keep trying it will eventuly sync it. Any help or insite anyone has would be greatly apperciated.

I suggest you refer the following thread. Windows 7 Sync Centre / Offline Files IssuesArthur Xie - MSFT

I've the same problem but i'm not synching from a Windows Server. I'm synching files from a DLink DNS323 network drive to my Windows 7 laptop. All my files fail to sync due to "The process cannot access the file because it is being used by another process" When i look at the status of the files on my network drive, it shows the folders as available offline, but files as not available offline
