Changing OWA 2003 Timeouts

Ever wonder how to change the default OWA timeouts for Exchange 2003
Here is the steps from Microsoft - http://support.microsoft.com/kb/830827

1. On the Exchange front-end server, log on by using the Exchange administrator account, and then start Registry Editor.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type PublicClientTimeout for the name of the DWORD, and then press ENTER.
5. Right-click the PublicClientTimeout DWORD value, and then click Modify.
6. Under Base, click Decimal.
7. In the Value data box, type a value that represents the number of minutes for the time-out. This number must be between 1 and 43200. (43200 minutes are equal to 30 days.) If you do not set a value, a value of 15 is assumed.Note The maximum possible value is 43200 for 30 days.
8. Click OK.

Important You must restart IIS for the changes to take effect. Also, if you set the TrustedClientTimeout value to a value that is lower than PublicClientTimeout, the TrustedClientTimeout value defaults to be equal to the PublicClientTimeout value. Likewise, if you set the PublicClientTimeout value to a value that is greater than the TrustedClientTimeout value, the TrustedClientTimeout value defaults to be equal to the PublicClientTimeout value.


However, If you are like me… and like command line, so here are the instructions for using the command line.

1. Reg add HKLM\system\currentcontrolset\services\msexchangeweb\owa /t reg_dword /v “publicclienttimeout” /d 30
2. Reg add HKLM\system\currentcontrolset\services\msexchangeweb\owa /t reg_dword /v “trustedclienttimeout” /d 30
3. Net stop w3svc
4. Net start w3svc

I personally think that my way is easier… :)
