(I don't know if its the right forum for this issue, if not tell me so.)

Hello,

wie have several Problems, here some observances:

1. Problem with our DLUs. A group of hardware identical computers, all identical cloned, mostly the profile will be loaded, sometimes not. After a while more and more workstations will not load the profile.

2. Looking in the Novell Zenworks management center, I noticed, that the displaying of assigned Edirectoy-objects often will be lost.

3. Registering workstations by hand using "zac reg -g https://192.168...." wil work about 2-10 times. Then I get the message, username/password will be wrong/unknown (from allways the same batch-file!).

4. I found, that logging on the Zenworks server console and restarting the server by using "novell-zenworks-configure -c Start" will help for problem 2. and 3. (for number 1. I am not shure).

5. In zcc.log I find en exception about a lost LDAP-connection (the ldap-server is in the same network) (see below).

What's going wrong or where shall I search for the issue?

Holger
