Solution 2

Take a look at this codeproject discussion:

http://www.codeproject.com/Messages/3000519/Re-WebRequest-GetResponse-equals-error-407-Proxy-A.aspx[^]

try using

poProxy.Credentials = CredentialCache.DefaultCredentials

instead of

oProxy.Credentials = New NetworkCredential(UserName, PassWord, Domain)
