i was having the same
LDAP://XXXXX: An operations error occurred.
problem. The errors keep reoccuring and eventually can cause out of memory errors.
The issue with the LDAP error for me was that the account used to start the DSC service was not a domain admin account. The server i was installing QVS on was not the domain controller.
I have the same problem. DSC keeps disconnecting for that reason.

2.2.2010 09:47:03.1748277 Information (ActiveDirectory.ActiveDirectoryProvider) Looking up RootDSE: LDAP://xxxxx.loc/RootDSE
2.2.2010 09:47:03.2529532 Warning (ActiveDirectory.ActiveDirectoryProvider) Exception while initializing LDAP://xxxxx.loc: The directory service is unavailable.
Now i have changed the service user from local to domain user(which is naturally in Qlikview Administrators Group). Hopefully this will work.
The solution was to set up a Service account in Active Directory, put it in the Administrators and QlikView Administrators groups on the server, and set it to run the QlikView services. The account can log onto the QlikView server and run services, but it has no privileges outside the QlikView server machine on the network.
Hope this can help someone else!
