New iMac running OS 10.8.3 can't connect to Server

[DHG]

We have an older SGI server running Unix from aprrox 2002. Not sure what version of Unix that this is running. We are unable to connect to the server (AFP). Other Macs we have we can connect, but they are running 10.6 or 10.7. 10.6 connected no problem out of the box. For 10.7 we had to put some code in Terminal to connect. No big deal. It appears Apple has dropped support for AFP. Several calls to Apple support and it appears we are SOL. Did a lot of poking around doing web searches, but wasn't able to find a solution. Has anyone else experienced this and is there anything we can do to get this machine to connect?

At this point we may just send the Mac back and try to find a "newer" iMac that is running 10.7. Thanks Apple.

Have you tried connecting via SMB? That may or may not work. But we use only SMB now and don't use AFP for anything.

Apple changed AFP in the last two versions. I had the same issue trying to connect to old Windows 2000 servers before we switched everything to SMB so we've basically retired those servers.

Yes, tried SMB. Does not connect at all. AFP gets a prompt for user name and password, then says it can't connect.

Run that terminal command again. You need to do it in Mountain Lion too.

Tried that. That worked for macs running 10.7. Unfortunately it does not resolve the issue in 10.8.3
