Crazy Windows 7 problem - PRIZES for a solution !!!

[Subliminal Aura]

Seriously this one is KEERRRAZY !

My Windows 7 box sees all the machines on the LAN but 'semi' sees one machine, let's call it media

All other machines see media fine... I can ssh into it, network shares all work etc etc

There are no firewalls or ipsec on any of the machines.

Problem

From this windows 7 machine I can see network shares on media but can't connect to them. I can even ssh in to the machine but if I try to run a command, I never see the output - so this leads me to the theory that there's a tcp/ip communication problem.

Here's the weird bit ... I'm still on the windows 7 machine and I decide to fire up a virtual machine now that virtual machine has full access to the media machine unlike it's host ... WHAT THE !!!!!!!

Crazy indeed .... Any suggestions ?

Any anti-virus programs such as Norton or McAfee making their own rules up?

Tried checking the advanced sharing options in 'Network and Sharing Center'? There might be something out of place there on the windows 7 machine. Also, what OS are the other machines running on?

Isn't Advanced shared just for folders on the local machine ?

The target machine (media) runs Ubuntu. Rest of my machines on my LAN run a mixture of Windows 7 and Joli OS ... Even my android devices seem to access the media server without problems.

As I said ... I can see network shares from other machines but the problem is with one machine in particular 'media'

The share is visible but when I click I get the following message after a very long wait ...

'\\media\root is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.'

'The specified network name is no longer available'

Works find on all other machines bar this one

This problem only just happened a few days back - I'm bewildered :/

Nothing in event viewer other than a warning that I'm about to investigate...

Wininit

Custom dynamic link libraries are being loaded for every application. The system administrator should review the list of libraries to ensure they are related to trusted applications.

Disabling is not enough in my experience, you need to remove it to be sure.

Still no dice... Uninstalled + rebooted.

Could it be that my network credentials are cached somewhere, maybe removing those might help ?

NOOOOOOO WAY !!!!!

I've just solved it but am not happy with the solution...

Changed the network adapter settings from MTU 7000 -> MTU 1500 :/

Now spec me an AV since I've uninstalled AVG

 

[rah^]

AVG?
