Netbios OK but no TCP/IP 1

[neilabbott]

SoHo network; Peer to Peer; ADSL Router and VPN Router; Mix of Win2k and Win98 machines. Win2K SP4.

Problem: All machines but laptop can access Internet.

My Win2K Dell C840 laptop shows all machines on network. Laptop can successfully ping all others by IP address and machine name. Pinging to internet names and IP addresses fail.
Explorer shows all mapped drives - files can be accessed/copied etc.
But; Laptop cannot see internet/no e-mail nor can it connect Winfax to Winfax Host on another machine. Winfax error says "RPC Server unavailable or name not found on server".
CommView program shows only NetBios action, no internet stuff.
Problem appeared after taking Laptop out of dock station to DVD Player/Recorder (trying to copy avi file to DVD machine!). Ran "DVApp" with firewire link to DVDR machine. DVAPP showed "camera device found" but no show on DVD/TV. Left Laptop running on battery while searching web for help. Went back to Laptop; battery run down; Laptop in hibernate (yellow light on). Left Laptop as it was.
Took out firewire cable and returned to office. Put Laptop back into dock station. It powered up but DVAPP reported accessing device. Tried closing DVAPP but it failed. Had to hit the "end now" in 'notresponding' dialog.
Shut down laptop and rebooted.
This is when problem started; NetBios stuff OK but no internet and no Winfax connectiion to Host.
(Event log shows "DCOM unable to communcate with COMPUTERNAME using the configured protocols"
Also; cannot print to network printers "printer name not found on server".
Status;
McAfee Firewall is off; VirusScan is on.
All TCP/IP settings as normal (static IP confirmed via IPConfig). (Netbios over TCP/Ip is on)
Services show RPC locator and other RPC service started.
SFC was run. It failed with the 0000016a error (RPC not available) . Followed MS's fix with copy of Verisign certificate from another Win2K machine. SFC /Scannow ran OK. rebooted. SFC OK - Problem still there.

Uninstalled TCP/IP. Rebooted. Re-installed TCP/IP - problem persists.

Tried dial-up to internet. problem persists - no web pages.

NIC card 'configure' shows card is OK.
hardware manager shows all OK

I have two local area connections (#2 and #3). #3 is the docking station version) this is the one I uninstalled and re-installed. #2 I think is the undocked version (shows 'unplugged'). I haven't tried uninstall/re-install
this one. Maybe I should try uninstallng both to clear *all* TCP/IP settings? Will this clear the TCP/IP stack? is my stack messed up?
... Just tried uninstalling #2 - it uninstalls #3 as well - they are on the same NIC.... (but they have both been there before the problem anyway.

I see XP has a NETSH command line option to reset the stack. Win2K doesn't!

My tether is now stretched to breakpoint. Am I up for a total reload of Win2K?
All offers of guidance accepted gratefully.

try running this ...

I see bcastner who contributes on here swear by this fix, and I myself have had it fix odd TCP/IP related issues.

Your problem sounds like a DNS failure though, have you tried seeing if nslookup is pointing to a valid DNS server?

hope the utility above gets you squared away. good luck.

Wizard! - the winsockfix program has succesfully dragged me back from the brink of despair...
Thanks Jlong for passing on bacastner's hot tip. Superb - Hoorah for Tek-Tips.

Pre and post fix notes:-
1. After having uninstalled TCP/IP I went to re-install before using the Winsockfix program.
Shock horror - no TCP/IP protocol listed! Disaster!
In desperation I 'added' IPX thingy - then realising It was not what I wanted I unchecked IPX. System deamnded a reboot which I did.
Then I go back to add protocol and hey presto! TCP/Ip is back on the list again. Phew!
Setup IP addresses again and then rebooted.
Ran fixer program and all is well.

After the joy of seeing TCP/IP fixed, Winfax Pro popped up and told me it was having problems with TCP/IP... I went to reset the progam's connection to the Winfax Host and all seemed Ok. But - no web browsing again - doh!
Stopped the Winfax service; still no go.
Rebooted. Winfax pops up saying problem with TCP/IP. This time I just let it go and leave Winfax not running.
Re-ran fixer program and then all OK again - web browsing fine.

Tried to uninstall Winfax and it wouldn't.
Methinks Winfax has not got its TCP/IP system properly designed and errors have crept in to the point where it f***s up the registry.
Shame 'cos the program suits me fine with its link into Outlook. Ah well them's the breaks.
Once again thanks for the tip.
Can sleep easy again!

I spoke too soon about the success.

The Winsockfix utility did fix the problem but only temporarily.
I went to install SSH Sentinel for my VPN and it flunked. Said there was a fault with TCP/IP stack.
When it exited my contact with internet had gone. Ran Winsockfix again and got it back.
I tried uninstall TCP/IP, rebooted, re-installed. All Netbios stuff is OK but no internet.
nslookup says my DNS (local ISP) is not there.
I run Winsockfix and it comes back and nslookup is fine.
I uninstalled TCP/IP and the 3Com network device as well, rebooted. Win2K found the card and re-installed it.
I added TCP/IP without problem but again, no internet.
Ran Winsockfix and all comes back to life once again.

Something is really screwed and I fear I will have to resort to re-load Win2k from scratch (aaarggggh!) all those patches/updates/fixes plus my quirky settings for Office and Outlook - yecch.
Maybe Agent Smith could nip in and sort it out???

Check your Winsock stack using the diagnostic procedures outlined in this article:

http://support.microsoft.com/?kbid=811259

From your description the problem lies with SSH Sentinel.

Thanks for the link - it is disconcerting to see no references in the KB to Win2K - it's all XP oriented.
THere are many referecnes in MSconfig to McAfee so I may uninstall McAfee everything (firewall has been off but VScan is on).
More soon

 

[bcastner]

If you remove McAfee I can gaurantee you that you will need to the Winsockfix utility.
