The following problem has only recently become an issue. On our server(winS'08), we have a shared network drive that serves as a file dump. My winXP machines will post files in the share and I will attempt to access them on my win7 machine. Occasionally, the files do not show up instantly and I can wait ~3-5mins and they will appear. When posting files on the inverse, from win7 to the XP machine, there is never any lag or delay. So far as I can tell, I have two options when this happens: wait it out or disconnect/reconnect to the share.
