Hi all,
I would like to ask If you have come accros a simimilar issue regarding changing the ArcGIS Server service account password using the ESRI Configure ArcGIS Server Account utility in windows start menu. The problem I'm having is that when I try to set new password I get an error. "Invalid password specified for arcgis" as show in picture below. I have found this ESRI post that is giving a different method to change the password althou I¸m not sure If it is the correct way of doing this. I have not try using the comandline version of this utility as of yet.

Thank you.
