Hi Guys I appreciate that this is not really the forum to post this question but sadly I have very limited web access at the moment: limited to work premises only and an over zealous web proxy I'm trying to setup a new media server for someone (just using xp pro) but im getting an error when trying to access various files of diferent lengths from one of the clients, be it either a laptop which shows "The Specified network name is no longer valid" or the Xbox which just freezes (its error handling isn't as advanced as windows . After acknowledging the dialogue on the laptop client I can then re-open that browse box fine with no delay or issue - i still can't copy the offending files though. As said, this only happens on *some* files. For example I have copied all of XBMC (a few thousand files of various lengths, a few bytes to 5 meg) and one of the couple of files that won't copy is only 132k in size! Now here's the details: The files which get stuck are of diferent types and lengths and just will not network copy using smb. The files are not corrupt and can be copied/deleted/viewed/edited on the server. Its not an NTFS security issue. Event logs show no information regarding to this on either the media server or laptop. It's all running over a Linksys 54g network and all other network functionality appears to be fine. The Xbox is using XBMC. The laptop and server are both XP Pro SP2 patched up to the very latest levels. I've run this through google and technet without any luck. Two MCSE's and I can't solve it, so i'm looking for a self-taught guru with a stroke of genius to save me (and my hair!). Please, someone save me!
