Indeed, I see the following lines in the output now:

-------------------------------------------------------------------
[2007/06/22 22:33:58, 10] lib/util.c:name_to_fqdn(3013)
  name_to_fqdn: lookup for PDFMAKER failed.
Failed to set servicePrincipalNames. Please ensure that
the DNS domain of this server matches the AD domain,

Which they don't:

-------------------------------------------------------------------
root at pdfserver:~# nslookup pdfserver.infotecsys.de
   Server:         10.162.2.3
   Address:        10.162.2.3#53

   ** server can't find pdfserver.infotecsys.de: NXDOMAIN

root at pdfserver:~# host pdfserver.infotecsys.de
   pdfserver.infotecsys.de does not exist (Authoritative answer)
-------------------------------------------------------------------

However, I do not really understand why this is the case. After
all, I've a valid entry for pdfserver in its local /etc/hosts, and
I have in /etc/nsswitch.conf a line

   hosts:   files wins dns

Shouldn't the latter therefor at first try to resolve the pdfserver
from the hosts file?

(BTW, I now also added an entry for pdfserver in the DC's
"%windir%\system32\etc\drivers\hosts" file, to no avail; I'm still
trying to figure out how to teach the ADS DC's DNS service what IP
address the pdfserver uses. Tomorrow I'll try to teach myself that
Windows trick...).
