Equipment is CS1000E rel 7.5. Installation is new. The Sig servers have been programmed with all required patches and the SU. The deployments have been done and everything looks fine. (It all looks the same as another system when doing a stare and compare) The problem is that when I go into element manager to build the Node there are no sig servers in the pull down box. I have heard of this problem before on rel 7.5. Does anyone have a idea what has gone wrong?
