Final Update: XP SP2 – ActiveX "Add-on" Blocking – Companyweb – OWA Issues Resolution

Updated 5th January 2005 after final testing with Microsoft (I have also removed the other blog post on the same issue so as not to confuse)

Today I got the magic email from Microsoft on what CLSID’s to allow to get RWW and OWA working on XP SP2 Machines that are working under an “Add-on” IE policy on your domain.

RWW Specific

{F414C260-6AC0-11CF-B6D1-00AA00BBBB58} – Javascript
{B54F3741-5B07-11cf-A4B0-00AA004A55E8} – VBScript
{7584C670-2274-4EFB-B00B-D6AABA6D3850} – Microsoft RDP Client Control

OWA Specific

{8D91090E-B955-11D1-ADC5-006008A5848C} – GEGetBlockFmtNamesParam Class

{2D360201-FFF5-11D1-8D03-00A0C959BC0A} – DHTML Edit Control Safe for Scripting

{2933BF90-7B36-11D2-B20E-00C04F983E60} – XML DOM Document

{F6D90F11-9C73-11D3-B32E-00C04F990BB4} – XML DOM Document

{F6D90F16-9C73-11D3-B32E-00C04F990BB4} – XML HTTP

{ED8C108E-4349-11D2-91A4-00C04F7969E8} – XML HTTP Request

{3050f4f8-98b5-11cf-bb82-00aa00bdce0b} – Microsoft Html Component

{B45FF030-4447-11D2-85DE-00C04FA35C89} – SearchAssistantOC

{8856f961-340a-11d0-a96b-00c04fd705a2} – Microsoft Web Browser

WSS specific:

{3050F819-98B5-11CF-BB82-00AA00BDCE0B} – HtmlDlgSafeHelper Class
{47B0DFC7-B7A3-11D1-ADC5-006008A5848C} – DEInsertTableParam Class

Office ActiveX Specific

{E18FEC31-2EA1-49A2-A7A6-902DC0D1FF05} – Office 11 name.dll

Now you can secure down the network from installing the “nasties” and keep your SBS2003 network running smooth.

Thanks to Dayne in Microsoft PSS for putting the pressure on to get this information!
