Hi,

I have a weird network problem on one of our Win2000 Pro workstation
systems.

Symptoms:

* Can ping other systems on the network (ip address only)
* Can map and use network drives
* Can't start TCP connections - this means that all services that use
the network (e.g. DNS) fail

In the output of "netstat -a" we can see the established TCP connections
to port 139 on the server (i.e. the mapped drives), however when we try
to telnet to the same port on the server we get connection refused.

Any ideas?


Dave.

Hi David - Try restoring your Winsock2 stack. From my Blog, Defending Your
Machine, here: http://defendingyourmachine.blogspot.com/


Download both a copy of LSPFIX here:
http://www.cexx.org/lspfix.htm

AND a copy of Winsockfix for W95, W98, and ME
http://www.tacktech.com/pub/winsockfix/WinsockFix.zip
Directions here: http://www.tacktech.com/display.cfm?ttid=257

or here for Win2k/XP
http://files.webattack.com/localdl834/WinsockxpFix.exe
Info and download here: http://www.spychecker.com/program/winsockxpfix.html
Directions here: http://www.iup.edu/house/resnet/winfix.shtm

The process of removing certain malware may kill your internet connection.
If this should occur, these programs, LSPFIX and WINSOCKFIX, will enable you
to regain your connection.

NOTE: It is reported that in XP SP2, the Run command

netsh winsock reset

will fix this problem without the need for these programs. (You can also try
this if you're on XP SP1. There has also been one, as yet unconfirmed,
report that this also works there.) Also, one MS technician suggested the
following sequence:

netsh int reset all
ipconfig /flushdns

See also: http://windowsxp.mvps.org/winsock.htm for additional XPSP2
info/approaches using the netsh command.

An alternative approach with necessary .reg files which will often work even
when the above doesn't is defined here, courtesy of Bob Cerelli:

"The process of removing certain malware may kill your internet connection."

Interesting. The important detail that I neglected to include in my
original posting was that Microsoft Anti-spyware was used in the last
day or so on this machine.

Thanks for your help, I'll give it a go.


Dave.

Success. I ran WinsockxpFix.exe only, and everything is working perfectly.

Thanks for your help.
