A little while back, I posted about issues with IE6 and Microsoft CRM.  These issues really have to more with IE6 than with CRM as there are simply a load of bugs in the browser that would cause any high-end web application to have problems.  You can read my previous post here:

http://www.ascentium.com/blog/crm/Post520.aspx

I wanted to update this post and call out two important notes.  The first is that IE6 “issues” don’t always appear as partially rendered pages.  They also appear as frozen screens, random lockups, slow performance and plan old crashes.  These are especially true when HTTP Compression is enabled.

The second point I wanted to call out is that Windows XP Service Pack 3 actually addresses a number of these issues.  This is good news for many organizations that (ugh) are still on IE6 and don’t want to move to IE7 and have users that have Windows XP machines.  This however is bad news for customers who are still on Windows 2000 SP4 with IE6 – as the fixes I am about to list below are only for the XP flavor of IE6 and since Windows 2000 is out of support won’t be coming to that platform (disabling HTTP compression though still helps).

Anyway, I have compiled a list of fixes in Windows XP SP3 for IE6 that I found noteworthy.  I have also highlighted the ones that are most likely to affect CRM because of the underlying technologies CRM uses:
