Greetings, I've been running for almost 3 years with the same config and now I needed to change all the IP numbers. I was able to use a combination of HARM and the console connection to the HiPer Arc to get the IP changed on the Arc and the IP pool changed but the problem I'm having is with the NMC. I changed the user interface information on the NMC in the TCM and clicked the Set button but after changing the IP on the NT box where I run TCM and the accounting stuff I can't ping the NMC and can't bring it up on TCM. If I change the IP on the NT box back I can see the NMC using TCM and the information I put in there is still there. I haven't been able to console into the NMC either. Do you use the same cable that you console into the HiPer Arc with? Thanks for anyhelp, Ray
