SYMPTOMS
When Microsoft Internet Explorer displays a Web page that uses Remote Data Services (RDS), an access violation may occur in Internet Explorer, and you may receive the following error message:

Microsoft Internet Explorer has encountered a problem and needs to close.

The Instruction at &quot;0x779d910a&quot; referenced memory at &quot;0x047ea000&quot;. The memory could not be &quot;read&quot;



CAUSE
Under stress, the URL is pushed against the end of a block of memory, and ActiveX Data Objects (ADO) incorrectly tries to copy bytes of data from beyond the end of the URL string, which is memory that does not belong to the process.
