HP LaserJet P4015 intermittently displays 49.4C27 Error message. All printing halts and printer has to be rebooted to being printing again.

HP Support recommends updating the printer firmware to version: 04.049.3, but it has been reported this error occurs with the new firmware as well.

Navigate thru the printer menu (on the front panel LCD display)
Configure Device
Embedded Jet Direct Menu

Disable ALL protocols that are not being used and are not configured.

Such as, if you are only using TCP/IP protocol, disable IPX/SPX, disable Appletalk, and disable DLC/LLC.

To disable a protocol:
navigate to the protocol

In Outlook, How to grant Send On Behalf Of permission?

Grant Send on Behalf of via Active Directory Users and Computers

This procedure will allow system managers to grant users the ability to send on the behalf of other users:

  1. Log onto the server running Exchange.
  2. Run Active Directory Users and Computers.
  3. Find the user's account that you want to be able to send on behalf of, and open up the account properties.
  4. Select the "Exchange General" tab.
  5. Click [Delivery Options...]
  6. Click [Add ...] and add the user (or users) that are to be granted permission to send on behalf of this account.
  7. Click [OK] to close the "Delivery Options" dialog.
  8. Click [OK] to close the account properties dialog..

How to Send a Message on Behalf of Another

To send an email on behalf of another (assuming you have been granted the necessary send-on-behalf-of privilege):

  1. Start Outlook.
  2. Go to your Inbox.
  3. Click [New] to start a new mail message.
  4. If the message does not show a "From" field then pull down the "View" menu and check "From Field".

    Note: I have noticed that if you have Outlook set to use Microsoft Word then the "From Field" does not appear in the "View" menu. The work around is to clear the option to use Word (Outlook → Tools → Options → Mail Format → Use Microsoft Office Word 2003 to edit e-mail messages), you will then be able to show the From field, and this remains even if you re-select to use use Word to edit emails.

  5. Click [From...] and select the account that you wish to send an email on behalf of.
  6. Compose the email as normal.


  • When you try to send the email you will get an error if you have not been granted the necessary send-on-behalf-of permission.
  • To the recipient the email will show both the true author and who it was sent on behalf of.

These notes have been tested with Exchange Server 2003, with Outlook 2000 and Outlook 2003. It is believed they also apply to Exchange Server 2000.

Event ID 9646 is logged in the application event log of your Exchange Server 2003 computer when a client opens many MAPI sessions

On a server that is running Microsoft Exchange Server 2003, an event that resembles the following event is logged in the Application log:

Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 9646
Closing Mapi session "/o=Organization/ou=Administrative Group/cn=Recipients/cn=Recipient" because it exceeded the maximum of 32 objects of type "session".

When this issue occurs, you may also receive the following error message in Microsoft Office Outlook 2003:
Unable to open your default e-mail folders. The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server is down for maintenance.
  1. Click Start, click Run, type services.msc in the Open box, and then click OK.
  2. Click the MSExchange Information Store service, and then click Restart Service.

First of all this error has nothing to do with Vista SP 2. It is really simple to fix.
Go to run and type outlook.exe/resetnavpane
