Subgrids are not displayed/loaded for some users / error messages in Fiddler

Hi

We have a very strange issue.
We have user for which the Contact/Account Form does not load properly on the CRM test system when using pc A (=his pc). The subgrids on the Form are not displayed/loaded. For all other users it works fine. If the affected user uses a different PC let’s call it “B” (with his AD/CRM) it works fine. It also works fine when the users uses his PC A but connects to our CRM DEV system. Different org – but the same solution.

So we did run a Fiddler session for the affected user and PC A. and can see a few red lines in the session log. See attached screenshot.

There is an error saying:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""www.w3.org/.../strict.dtd">

<HTML><HEAD><TITLE>Bad Request</TITLE>

<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>

<BODY><h2>Bad Request - Request Too Long</h2>

<hr><p>HTTP Error 400. The size of the request headers is too long.</p>

</BODY></HTML>

 

We tried both IE/Chrome and as well cleared browser cache. But nothing helps.
Any other ideas?


Many thanks

Alen
