InfoPath Dev

Hi,

I am trying to access the active directory from the server to enable users to search for people to send an email. I followed the following blog http://blogs.microsoft.co.il/blogs/itaysk/archive/2007/04/05/InfoPath-_2D00_-Get-the-current-user-without-writing-code.aspx and when I replaced my server name, I get either an error message like"The file is not an valid XML file. There is not enough storage space", or I get a message as, "The file is not a valid XML file.The drive cannot locate a specific area or track on the disk".

I do have access to the server. I am not sure what seems to be the problem. Please help me out with this.

Thanks,

Shyam 

 I've seen this error sporadically in Infopath but have found no solution. I have noticed, though, that if I close Infopath and try the same data connection in a blank, new form, I cannot reproduce the error. Strange, right?

 Well, I just tried in anew form and I get the same error. I am able to remote into the server. But when I call the web service, I get 'cannot load a specific track'

:( This has been bothering me for days. Is there any other way to do this ?

Thanks,

Shyam
