Set Windows/AD password so that it “never expires”?

Question

Here is my code:

using (DirectoryEntry AD = new DirectoryEntry(\"WinNT://\" + Environment.MachineName +    \",computer\"))
{
   DirectoryEntry NewUser = AD.C         


        

Answer 1

*EDITED

For domain accounts:

int NON_EXPIRE_FLAG = 0x10000;
val = (int) NewUser.Properties["userAccountControl"].Value;
NewUser.Properties["userAccountControl"].Value = val | NON_EXPIRE_FLAG;
NewUser.CommitChanges();

For local accounts:

I believe you'd use "UserFlags" instead of userAccountControl
