We're experiencing a network issue from our remote locations randomly.
Clients are all Windows XP (sp1/sp2) connecting to Windows 2003 SP1 servers.
Frequently, they experience "hanging" SMB traffic, sometimes to different
servers (not all). What we see is that all connections from these remote
sites (across wan links, 4mbit), go into a TIME_WAIT status, and hangs.
Normal TCP traffic works fine, ie. ping, pathping, traceroute, ftp, etc..
So, in effect exchange and filesharing become inaccessible. Name resolution
is not a problem either. Ie. a net use to a share will work, however it will
never return any file listings. So what it looks like, is that the server
responds, but no smb traffic goes back to the client. Local users have no
issue when this happens. So far the only thing to fix this, is to reboot
the server. This happens approx. every week or so. There is no firewall
between the remote and local site. HAve anyone experienced this problem?
Any feedback appreciated.
