Linux / Samba/ Shared Files / Error

Heya guys...a quick run down.

I have a Linux/Samba server I use at my work. We have about 18 users that connect to it on a daily basis. All these users are on our corporate network.

We have two buildings...Dispatch which has subnet of 192.168.30.XX and then the Shop...about 2 MI away, which has a subnet of 192.168.90.XX

The Linux server is completley fine, and everyone on the 192.168.30 subnet can view it fine, and it works perfectly. I cannot though get the .90.XX subnet to connect to it.

I allowed the subnet in the "Host Allow" list, and I can ping all the computers on the .90.XX subnet from the .30.XX subnet, and they can ALL ping the samba server, and EVERY other computer on our Quickway-CSI workgroup over here at Dispatch. (basically, every PC can ping one another)

Basically, I cannot connect to my linux box from ONE subnet to ANOTHER. I can ping it, however; when I try to bring up my 192.168.30.XX/public folder, I get invalid Network Path, or invalid Network name. I throw the .90.XX computers onto the Quickway-CSI work group, and under Windows "view workgroup" computers nothing shows up.

Anyone know why I can ping it, but not bring up a window to explore the shared files?

Thanks Guys!
