procInst = conK2.CreateProcessInstance("INTERNALSERVICESLeaveApproval");

INTERNALSERVICS = Project Name   ??

This is a Plan Page :

        Dim myconn As New SourceCode.K2ROM.Connection
        Dim myproc As SourceCode.K2ROM.ProcessInstance
        Dim strCon As String
        strCon = "[;];Authentication=Windows;Domain=domain;User=administrator;Password=password"
        myconn.Open("ServerName", strCon)
        myproc = myconn.CreateProcessInstance("ProjectNameProcessName")
        myproc.Folio = "ProcessinstanceName"
        myconn.StartProcessInstance(myproc)
        myconn.Close()

 Best regards.
 

With your server properties open, you should have a K2.Net Servers List. Click on your server. It should then show you the expiry date.
