ACS 3.2 Key mismatch

Unanswered Question
Sep 13th, 2010

I have inherited an ACS 3.2 system running on windows 2000. When i try to add a new switch using the same settings as previously working switches i get a "Key mismatch " in the failed attempts log. I have double checked that the keys are the same on the switch and in ACS. I have tried different keys as well eg 123456. I have also check that a NDG key does not exist. Where should i go from here to troubleshoot this issue?

I have this problem too.

Do you have any entry which is using wild card?

If yes, check them to see if there is a match there.

I don't have any wild cards as far as i can see in ACS. Below is some debug information from one of the switches:
