Intermittent internet problems on office manager computer

[chrbb]

Spent most of today trying to sort out problems on one of our office pcs. Three identical machines, same setup on it's own peer to peer network.

 

One computer will randomly log it's user out of E1 and teachers2parents, every so often they get the internet error page - with the test your dns etc etc, but have other internet expolorer pages open and functional. At first I kind of dismissed it as a "I need a shiny new computer syndrome ", but have got more puzzled as the days have gone on.

 

I've checked;

event viewer - no network disconections other the one I forced by changing network sockets

 

Ip config no different to two other computers

 

IE settings identical

 

network settings identical.

 

Changed network socket

 

Got office lady to try her E1 on spare laptop.

 

Suggested she swop computers with other office lady for the morning - went down like lead balloon!

 

Other than wipe her machine and start again - any ideas?

Rogue BHO?

 

Malware triggering a Firewall block event?

Hate to be "that guy" but have you tried a different cable? YOu mention socket.. But i once spent a day and a half on-site with a customer that had similar issues and it turned out to be a crushed cable..

Got to say, I’d be interested to hear what fixed this issue, or maybe the ticket is still open? [emoji23]
