I have 2 netware 6.5 sp8 servers with identical hardware, drivers and network configuration. All NICs are Broadcom B57 internal. I recently enabled jumbo frames on the 2nd NICs over private network. Both can be pinged, but backups fail on server 2 over private. Server 1 works like a champ. Also noticed that when I made changes to network config for troubleshooting, Server 1 would reinitialize in 1-2 seconds. Server 2 takes about 15 seconds to reinitialize.

Would this possibly be something that can be fixed by blowing away the netware reg files and letting them rebuild, or should I start looking for a new NIC? Thanks.
