Also, if you have a Stratagy ES, or IES voicemail connected with a network cable, the admin on the CTX can lock up at times. Softkeys also stop working.

Cycle power on the CTX.

MJ_Wald, since you said that you get the error immediately, that is probably not your issue. Double check IP address settings and try to Ping the CTX from your PC.

I have heard of probles installing emanager on a PC in a domain sometimes, but if you got to the point of connecting, I would not think that is the issue. Usually something goes wrong trying to install, or open emanager.
