Windows Service network connection

[George Jin]

My windows service program can not connect to the internet. But if it runs
as a stand along program, it looks perfectly and can connect internet. ANy
one knows why my windows service can not connect the the internet? and even
can not resole the host name by dns! following is my code snippet
HttpWebRequest aRequest = (HttpWebRequest )WebRequest.Cre ate(uri);

aRequest.GetRes ponse();
