Hi,
I have facing login credentials lost web server to wcf web service(different server). I got correct data if i open my web site from Web Server but i got "403 forbidden" if i call from client pc or other server. I used domain account to run the web
application for my own web site. Is it something wrong on my configuration at each server. I have no idea to how to make it to correct. I don't find correct answer on Google or bing.
Here is server information and SPN List
1. Domain Server
2. CRM Server (Web Site is host on this server)
- Enable Kernel Mode
- Windows authentication (1st - Negotiate, 2nd - Ntlm)
- Impersonate
- Application Pool (domain\account)
3. ERP Server (WCF Web Services is host on this server - support kerberos + ntlm).
- domain\account to run services.
- constrained delegation to sql server
4. SQL Server
I used DefaultNetworkCredentials in my asp.net to access the web services.
Here is SPN on each Server and Service Account

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.
The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
