Windows 7: Wired LAN dropouts

Wired LAN dropouts

Hi,

I have 6 computers wired to a server via two TPLINK ethernet switches.

The server is a linux box with Ubuntu 12.04 i386 and acts as a gateway to the internet. The server has its own firewall operating between the internet router and the linux box.

All other computers have Windows 7, Windows 7 firewall and Norman anti Virus operating.

Three of the computers have a requirement to access a MYOB file on the server. All was well until yesterday, when two out of the three stations had connections problems. All computers have no problems accessing the internet which is accessed via the server.

The Problem: Two of the computers consistently keep loosing connection to the file server which means we can't access the MYOB file except via one computer.

Is this a Windows 7 or a linux problem. Any suggestions?

Thanks

Max

I forgot to mention that originally, when trying to access the MYOB file and being denied access, the user was getting a message there was not enought disk space (less than 1 kb) yet when I did checked on the server there was about 131GB space left.

Update. Not Solved.

New server hardware has been installed. Software installed and data files restored. Problem still exists. Looks more and more like a networking issue.

Hello,

Sometimes a simple reboot of your server (if you have not done this yet) helps. Also, is there any changes in your network done recently before this issue occurred?



If it didn't help please let us know.

Thanks for the reply 2XG. Yes, tried the reboot. The situation has now deteriorated. Now no access from any computers but internet connectivity is still in tact.

No changes have occurred to the server. I am the only one able to access the server in an administrative capacity and I have NOT made any changes recently. I can login via putty though which makes me think the issue is on the server and permissions etc. I have also considered failing harddrive as being a contributing factor and/or a corrupt permissions file.

Am investigating problem could be caused by Norman anitvirus program's firewall. Turning off the firewall seems to improve connectivity. With firewall turned on I get a lot of activity recorded in the output from eLogger. I have written to the Norman await a reply.

I'd suggest to disable the Norman Firewall and use the Windows built-in Firewall. You may also uninstall and reinstall the program and see if that helps.

Norman has acknowledged its firewall has problems with connectivity with the LAN is working to resolve the problem.
