Exchange SP2 and SBS

Just finished up my first production upgrade to Service Pack 2 of Exchange 2003 on an SBS 2003 Premium box. Remember as many others have mentioned to uninstall IMF first if you installed it. On this first box IMF was not listed in the Add/Remove programs. How do you manually install? Beats me! :) Just install IMF v1 again and the program should present itself in the Add/Remove programs. Now you can uninstall IMF and install SP2 for Exchange.

Vlad has a nice write up on his blog of the SP2 install.

Remember 2 things for us SBS'ers.
1. You have to manually get IMF going again. From the Exchange System Manager, expand your server, then expand Protocols and SMTP. Right-click on the Default SMTP Virtual Server and select Properties. On the General tab click the Advanced button next to the IP Address drop-down. From the Advanced dialog box, highlight the appropropriate IP address and click Edit. On the resultant Identification dialog box, check the Apply Intelligent Message Filter check-box.
2. The default limit of the Exchange box doesn't just jump to 75 gig. You have to up the reg key. By default it does now jump from 16GB to 18GB. Here's how to change it:
a. Open a registry editor, such as Regedit.exe or Regedt32.exe.
b. Navigate to: HKLM\System\CurrentControlSet\Services\MSExchangeIS\Server-Name\Private-GUID
c. Change the "Database Size Limit in Gb" value (DWORD value if it's not there) to anything from 1 to 75. Remember to check your disk space available. You don't want the db to crash your server if it grows too high.
d. Close the registry editor.
