Terminal Services Event ID 6037

I recently struggled with this one for work, after I made a change to IIS on our terminal server (Server 2008 Standard).  I could not launch TS RemoteApps, as credentials were being consistently rejected, though correct.  The only error I could find in the event log was along these lines:

Log Name: System
Source: LsaSrv
Date: 10/27/2008 10:46:40 PM
Event ID: 6037
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: Gateway
Description:
The program lsass.exe, with the assigned process ID 572, could not authenticate locally by using the target name TERMSERV/ts.xxxx.com. The target name used is not valid. A target name should refer to one of the local computer names, for example, the DNS host name.

This error may also contain address "HTTP/ts.xxxx.com"

Thanks to Chad A. Gross on the http://www.vistax64.com forums, I was pointed at a blog with a solution: http://blogs.technet.com/sbs/archive/2009/05/07/event-2436-for-sharepoint-services-3-search.aspx.

Though the blog states a solution for a different problem, it worked just as well for me:

Click Start, click Run, type regedit, and then click OK.
In Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
Right-click MSV1_0, point to New, and then click Multi-String Value.
Type BackConnectionHostNames, and then press ENTER.
Right-click BackConnectionHostNames, and then click Modify.
In the Value data box, type the URL mentioned in the above warning event, and then click OK.
Quit Registry Editor, and then restart the IIS service.

For good measure, I restarted the server and bam, the error was gone.
