Exchange 2003 Database Size Limits

By default, Microsoft Exchange 2003 is preconfigured to limit the size of the Exchange Data file size to 16GB. If you have Microsoft Exchange 2003 SP2 installed you can use the registry to alter the 16GB limit to a larger size, anywhere up to 75GB. You can also add further registry keys that can:-

• Warn you when the Database size reaches a preset limit

• Configure the preset time of day this Database size check occurs

All of the Registry Changes are made in the following location:-

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<SERVER NAME>\Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00

ISA 2004 / ISA 2006 - Bypassing Web Proxy

You might find some of your network users cant access certain sites when behind a Microsoft ISA 2004 Server.

These sites could be online banking, ecommerce or other web site which doesnt like parts of its web site being accessed through a proxy server.

The trick is to modify your ISA 2004 configuration to add certain sites to a ‘Directly Access’ list.

You can find this setting in configuration, networks, internal network. If you double click on the ‘Internal Network’ and choose the ‘Web Browser’ tab, you can add your list of domains or internet addresses that you want to bypass the ISA 2004 Server Web Proxy.

Outlook “Cannot create file” error when opening attachments

Outlook 2007 displays an error message when opening an Excel attachment

“Cannot create file:” error

This can be caused by deleting the complete contents of your “Temporary Internet Files” folder. When you open an attachment in Outlook 2007, it uses a folder in the “Temporary Internet Files” folder as a temporary store for  the file attachment in Outlook.

To solve this problem, you will need to edit the registry, see below:-

Locate and click the following key in the registry using regedt32:
HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security\OutlookSecureTTempFolder

1) Make sure the path exists

2) Set the key to read-only for the user

HP2600N Print Quality Problems

Ever had a problem with a HP2600N colour laser printer where the Magenta is faded, even when you print the demo pages or supplies status print outs the Magenta is faded or washed out?

The self test and cleaning page come out fine?

There seems to be a design flaw with these printers. The Magenta cartridge sits in the bottom of the printer and over a period of time, Magenta toner leaks out through apparent normal use.

Toner dust builds up on the mirrors and lens inside the laser unit causes the fading. The only way to resolve this problem is to get the lens and mirrors cleaned.

I would advise getting this work carried out by a skilled technician, this procedure is not for the in-experienced. Incorrect repair of the laser unit can cause blindness , cancer or electric shock.

You are attempting to open a file that was created in an earlier version of Microsoft Office. This file type is blocked from opening in this version by your registry policy setting

We have noticed problems with Microsoft Office 2003 after applying Office 2003 SP3 updates.

Files created with earlier versions of Microsoft Office 2003 would not open and came up with an error message saying that registry policy would not allow the open of files from earlier versions of Word!

It seems that this block of older word files is a feature of Office 2003 SP3… It use is supposed to block some older Office document files which were created in earlier versions of Office. These earlier document versions could be opened in pre-SP3 version but are now considered possibly unsafe.

To re-enable functionality of opening previous versions of Office documents you will need to follw a Microsoft support document which will involve the editing of your registry.
