Webservice client gets no connection

Hi all,

I have some trouble with one PC in our LAN (PC001):

I wrote a "consuming" webservice app (C# .NET 2.0). I can't connect to a webservice (LAN or Inet) from this PC (Timeout), all other PCs can connect to both webservices with the same app ! I think, there is a permission problem on PC001. I wrote a HTTP-client (using HttpWebRequest) and started it on PC001, this works fine.

PC001:

- WinXP SP2
- IE7 (Browsing the internet works fine)
- no proxy server to connect to inet
- Ping an IP in internet works fine
- Firewall not active
- System.Web.Services.Protocols.SoapHttpClientProtocol doesn't work
- System.Net.HttpWebRequest works fine

Is there a difference beetween System.Web.Services.Protocols.SoapHttpClientProtocol and System.Net.HttpWebRequest Both connect on Port80 on the destination…
Is there a setting in WinXP to give a webservice security settings or other permissions

Thanks in advance

Hi all,

the problem was solved: A virus scanner (AVK) has blocked the data from the webservice on Port 80. I think, the scanner wants to block the possibility of trojaner to send data from the personal pc to the internet.
