If you are not using the built in "Administrator" account then you will have issues managing printers even if your account belongs to the Local Administrators or Domain Administrators group.
If you just right click on an existing printer and select "Printer Properties" you will get one of two situations if you are not using the built in Administrator account.
- If you have created the printer then when you try and do something such as modify a port you will get the "An error occurred during port configuration - Access is denied." error.
- If someone else had created the printer then many of the options will be grayed out
To get around this double click on the printer icon to open up the printer queue window
From the top menu select "Printer" and then "Open As Administrator"
If you are an administrator you will not be prompted for credentials otherwise you will need to enter in the administrator's credentials
Now go back to the printer menu and select "Properties"
You should now be able to modify all the settings without any restrictions
Print Server Properties
To modify the print server properties just click on any printer and then select "Print server properties" from the top menu
You will be able to modify the ports and other functions without restriction (as long as your account belongs to the administrator group)
