Some time ago nearly all workstations in our team (Windows XP SP2) exhibited intermittend but frequent delays when accessing shares on the network. Typically the first access to a share which hadn't been accessed for some time resulted in a nearly frozen workstation for up to 30 seconds. Then everything started working fine again.
Using TCPView from Sysinternals I saw that during this delays there was a connection to the netbios-ssn port on the file server which was in state SYN_SENT.
Disable NetBIOS over TCP/IP for the intranet network adapter.
Problem solved, but I didn't like to manipulate our centrally managed network configuration for the intranet.
Disable NetBIOS over TCP/IP only for the VMWare network adapter (VMNet1 used for host only communications).
Problem solved again!
- Why does NetBIOS over TCP/IP on one network adapter disturb NetBIOS over TCP/IP on another network adapter?
- Is this problem specific to VMWare network adapters?
- Has anybody else seen this phenomen?
- VMWare Workstation version 6.0.3
- At the time I started seriously analysing the problem it was no more possible to find out what had been changed to our systems at the time the problems started.
