Printer is an unspecified device and print spooler service is stopped

clock April 4, 2014 08:01 by author Ashwin Pai

In Windows 7 & Windows 8 , all your printers have gone. If you have a local printer that printer is listed as an Unspecified device.

I solved it the following way.

I found that the print spooler service had stopped. If I restarted the service but it stopped again.

I went to "%WINDIR%\system32\spool\printers" & deleted all the files in there.

I then started the print spooler service & it remained started.

Went to device & printers and all my printers had come back again & the local printer was no longer an Unspecified device.

Event ID: 27 While processing a TGS request for the target server krbtgt

clock May 12, 2012 12:59 by author Ashwin Pai

While processing a TGS request for the target server krbtgt XXXXXXXX
did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 8).
The requested etypes were 18.  The accounts available etypes were 23  -133  -128  3  1.

Event Type: Error
Event Source: KDC
Event Category: None
Event ID: 27

The cause of the event is that the client requests a service ticket with a etype 18 (aes256-cts-hmac-sha1-96), which is not supported by Windows Server 2003 but supported by Windows Server 2008 R2. If the Kerberos authentication works properly, you can safely ignore the events. It just informs the clients what etypes it supports.

For more information, please refer to the following articles:

The security principals and the services that use only DES encryption for Kerberos authentication are incompatible with the default settings on a computer that is running Windows 7 or Windows Server 2008 R2

This one drove me crazy. Many help articles start with  " start adsiedit and browse to CN=Configuration CN=Services ....." . I could not see CN=Configuration to save my life.

After hours of hair pulling I found this article Thanks David



If it helped would appreciate a rating star.

    This address is often the same as that of the Exchange server especially if you are running SBS

    Name: Application relay

    8b. select the Authentication tab & additionally check off  Externally Secured

That's it you are done.

 If you still cannot send email alerts , you will want to set the logging for the recive connector you just created to Verbose

You will find the log in the following folder.

Exchange 2007: C:\Program Files\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive
