TFTP Server Service Fails to Start - System.NullReferenceException

I just upgraded to the Engineer's Toolset version 10.0, and now my TFTP Server service will not start.

I have tried:

Running the TFTP Server application 'as administrator'.
Starting the service through the Services MMC.
Repairing the SolarWinds Engineer's Edition installation through Windows Add/Remove Programs.
Disabling UAC (User Account Control)

None of these have helpped. I am running Windows Vista (32-Bit) with Service Pack 1. I had the 9.2 version of SolarWinds installed on my system previously, and the TFTP Server worked just fine. I recieve the following error message in my Application Event Log:

   at System.ServiceProcess.ServiceBase.Stop()
   at TFTPServer.Service.TFTPService.OnStart(String[] args)
   at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

Any help is appreciated! I use this tool on a daily basis!

Thank You!

cmlunsford - Here is what you need to do:

Navigate to your installation folder; usually <program files>\solarwinds\Engineer's Tooset.

Then run this command line:

installutil /u "solarwinds tftp server.exe"

Reboot

Nav to same folder and run:

installutil "solarwinds tftp server.exe"

Should work fine after that.

HTH,

Curt - it looks like a port is in use... Either UDP 69, or our IPC port. Can you verify that there is not another TFTP Server already running on the machine?

HTH,

I tried this and still no go. Running Vista Business (32-bit) with all the latest patches. This used to work for me no problem. The appliaction event log error is identical to what was previously posted.

greg

awsl - can you please post the output of "netstat -a -b -n"?

*Edit Notice: command change (removed -p udp)

Thanks,

Greg
