Hi Thomas

Thanks for pointing that out. From what I'm reading (oddly enough from http://support.microsoft.com/kb/889588) SharingViolationRetries set to 0 seems to imply there is no need for SharingViolationDelay and SharingViolationTimeout. Is that right? What side effects could there be for other files/users? Would they see more errors from the server - even if they are not sharing a file or would they just get a faster reponse from the server when attempting to access a file opened by someone else?

UPDATE: Why would this make a difference? If there is no violation, then there should be no second attempts or timeouts or delays, right?

Thanks
