check if a service is runing

[cgj]

Hi all
I use pcanywhere to remote pooling for a few stores,
the problem is when pcanywhere is not waiting for a connection,
pcanywhere wait host is a service and it runs a exe,
the service executable path is C:\Program Files\Symantec\pcAnywhere\awhost32.exe
I cant just shell it because maybe its running,
is there a way in vb.net to check if the service is running if not start it?

Thank You
