Win2k3 has lots of file locking issues related to the network redirector. Either obtain the latest redirector patches (updates to mrxsmb.sys and rdbss.sys) or try SP1. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Stratton, Doug ISMC:EX Sent: Friday, January 20, 2006 12:13 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] What is locking files w2k3/cmfpsv3 r03/office 2003 Can anyone tell me how I can identify what process/executable is locking a file on a remote fileserver? We are having problems with peoples word and pst files getting locked and I would like to see what is hanging onto it. At this point I don't have admin rights on the file servers and we have just been asking the fileserver guys to confirm locked and unlock it. If what they see is the same thing I see when I use computer management and look in shared folders/open files it does not identify what is holding the file open. I wish to identify what is holding it open if that is what is going on? Or does some app start, open a file,lock it and if the app crashes? there is no reference to the app just that it is locked by that user?? Thanks for any info.
