Linux server not communicating on network... why?
 

I need some assistance with a Linux server...
Our business has a Linux server, running "SME Server", which is a preconfigured Linux server designed for small to medium businesses. It's currently handling an MS Access Database with 10,000+ members, and up till now it's been working fine.
Here's the deal... My server started to boot incorrectly and sometimes not boot at all.
I found the cause to be a completely full HDD, like 0 bytes free!!
I decided to ghost the server's 2Gb HDD onto a 20Gb HDD, which worked fine. It has a total of 5 partitions, and all were ghosted successfully.
After ghosting was complete, I used Partition Magic to upsize the storage partition from 500Mb to 15Gb, else it would still only amount to a 2Gb drive. I left the OS partition and swap space alone. So far so good.
The server now boots correctly again, with it's new HDD.
My problem is: The server will no longer talk to other (Windows) computers on the network, like they were before the ghosting. Neither can I re-connect the network drives on the Windows machines.
The server uses 2 ethernet cards, one for the ADSL router and the other to a switch (for the Windows workstations to connect to.)
What can the problem be? Technically the only change to the server is a larger storage partition... Or is it?

Hope someone can help!!

In theory what you did shouldn't cause any problems, but sometimes funny things happen. Have you checked to see if the SAMBA service is running? If not look in its logs for the reason why it failed to start.

Edit to add: Are you accessing the machine remotely? Does it respond to pings from other hosts?

Hi,
I'm not very familiar with how Linux works. There is a service called "SMB", which appears when the server is booting, and it's status is "OK".
Also, SME Server doesn't seem to work like Linux systems I've seen in the past... I can login to the root account, but it seems to lack many of the usual Linux commands (or so I was told).

The server is conneced to a Windows network and has worked fine in the past, up until the HDD upgrade.
Since then I have been unable to ping the server from the Win98 machine connected to it.
