i could see my sharing files by ip address but i couldn't open this filess so i decided to change my registry and changed this address key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer
and then i can't see my sharing files and tell me "network path was not found "
(I can't figure out what you might have thought would help -- LanmanServer is a key, all the interesting stuff has values under that key, but you have not mentioned any. And besides which nothing there is likely to help the "couldn't open this files").
Yeah, that was a bad idea. There seems to be at least a few values there that are probably system-specific. Which means there's no-one that can tell you what your system used to have. Perhaps a backup would have been prudent? Too late now.
Perhaps uninstalling Microsoft Networking and then reinstalling it would help? I dunno.
