Message Check in the services file located in c:\winnt\system32\drivers\etc . Look for a port number that matches that found in the %SDEHOME%\etc\services.sde file. If not add it.
It should look like this.
esri_sde 5151/tcp

Make sure if it is at the end of the file that there is a blank line that follows it.

Message Hi,
are you trying to configure several ArcSDE services on the same server ?
If so, there is something to do about the %SDEHOME%. You can have a look on your Arcsde Installation Help to "multiple installs".
If not, I've no better idea.

Regards.

Message This may be a little late to help with this situation but, I had the same problem and wanted to respond with the fix that I came up with.

I found that during the post installation process the giomgr.defs file was in some way being referenced by a component in the process. This seemed to be causing the problem. So, the work around that worked for me:

before running post installation setup
1) Navigate to your ArcSDE\sqlexe\etc folder
2) Make copies of the goimgr.defs, dbinit.sde, dbtune.sde files
3) rename files to
giomgr_{any name}.defs
dbinit_{any name}.sde
dbtune_{any name}.sde

4) Run Post Installation Setup
5) at the ArcSDE Configuration files selection screen, select User Custom file and navigate to and select new copies of the configuration files.
6) Continue with the post installation setup.

Post Installation completes and the created ArcSDE service starts.

Message This problem can also occur if you don't register SDE after every database repository you create. I have a "vector" and a "working" database with one service for each, and I couldn't get my service to start for the working database because I mistakingly that registering the software once was enough.
