For an NT based Presentation Server (WinAppxD), see the FAQ “Service is not running” for debugging approaches. Also for NT Presentation Server:

1) Bring up the Task Manager and look for a WinAppxD process, which should tell us whether WinAppxD is running.

2) Running "netstat -a" and looking for "*.8060" (for example) in the "Local Address" list will tell you if anything is listening on the port. For example:

C:\WINDOWS> netstat -a Active Connections Proto Local Address Foreign Address State TCP oz:1079 P66:0 LISTENING TCP oz:1650 P66:0 LISTENING TCP oz:1656 P66:0 LISTENING TCP oz:1533 P66:0 LISTENING Services for WinAppxD has a radio button giving alternatives for 'System' or 'This Account:'. The latter should be on, with UserID equal to the APPX user set up for this Presentation Server. Try reentering the password for this User Account. Then Re-IPL.

For a Unix based Presentation Server:

To see what Presentation Servers are running, execute: ps -ef | grep appxd To see what ports (prefixed with '806') are being listened to: netstat -a | grep 806 Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp 0 0 *.8064 *.* LISTEN tcp 0 0 *.8068 *.* LISTEN tcp 0 0 *.8067 *.* LISTEN.
