Could not read the status of Windows services...since 2.3

Hello all,

Since upgrading to 2.3 (stack installer on openSUSE 10.3), almost all of my Windows servers are getting the following error:

Could not read the status of Windows services (NT_STATUS_ACCESS_DENIED). Check your username/password settings and verify network connectivity.

I was NOT getting this with 2.2.4, so it's not a question of credentials!

I checked the zenwin log and it's full of the same messages:

...over and over again.

Any suggestions would be appreciated.

Thanks!
