Thanks for your response Philip,

Since the local success behavior is not machine specific, we can start
checking in the .NET CAS setting. Would you please try the following test
first:

For .NET Code Access Security, we can configure it through

Control Panel--->Administrative tools--->.NET Framework Configuration tool
or caspol.exe

#Code Access Security Policy Tool (Caspol.exe)
http://msdn.microsoft.com/library/en-us/cptools/html/cpgrfcodeaccesssecurity
policyutilitycaspolexe.asp?frame=true

We can simply start from caspol.exe. Open the VS.NET's commandline window
and execute the following command which temporarily turn off .NET CAS:

caspol -s off

After that, no .NET CAS checking will perform at runtime. Then, please try
running the INFO PATH form (from sharepiont library) again to see whether
it works. If this can work, we could make sure the problem is caused by the
infopath running from sharepoint library is restricted to a certain
security zone which hasn't permission to adjust Credentials of
httpwebrequest. And we should manually add a custom code group in CAS
group to grant the components from the form library the sufficient
permissions.

Anyway, please let me know what you got and if there're anything unclear,
please feel free to post here.

Thanks,

Steven Cheng

| It was the non-development machine that I had been testing the form from,

|
| Please tell me what steps you'd like me to take to check the CAS setting.

| Thank you.
