Starte eksternt program under bestemt bruger
Jeg forsøger at få min asp.net 2.0 applikation til at starte et program, men det skal være som en bestemt bruger. Jeg bruger calc.exe som eksempel.Først lukker den alle eksisterende calc.exe processer ned. Dette virker fint. Den får også logget ind på den rigtige bruger.
Men den får ikke startet calc.exe igen...
