Network Cable Issues

[Ian]

This is a strange question, but I have a cross-connect network connection that goes down on a server (Win 2k3) and it looks fine at both ends (active and servers fine, nothing in events manager).

I can't ping the other machine etc.. however if I disable and then re-enable the connection, it springs back to life?

Would this be symptomatic of a problem with the actual cable? I've doubted it, but there doesn't seem to be any software possibility left.

(Its a remote server - however its being replaced anyway, but I'm sceptical!)

if you've got a multimeter check the resistance of the wire while wiggling it, you might find the connection in the plug is loose

 

[Techy]

are you pinging the IP or hostname?

 

[Ian]

Techy, IP only - but next time it happens I'll try hostname.

Me__2001, I can't check the resistance unfortunatly as the server is in the US. They are replacing the cable but I just doubt it would be the problem

 

[Techy]

don't bother Ian, if it won't ping the IP it's very unlikely to ping hostname, unless you're pinging the wrong IP

I've come across this before, will try and dig out fix.

IIRC it's yet another problem with the Windows TCP/IP stack.

 

[Techy]

is the server logging anything in the event log? and i assume its 2K3 server?

 

[Ian]

Yeah its 2k3 but nothing appears in the event log. I've gone through IPSec, Firewalls etc... but nothing turns up. Both servers seem to work fine.

I've got a script that restart the connection within 1 minute should it go down, so its not too bad - but not ideal.
