Win Mobile 6 Pro connect to ThreeTier ser.: ANONYMOUS LOGON

dakyn

Hio to all,
I create little application on Windows Mobile 6 Pro and It connects to NAV webservice.
When I connect to webservice I pass it login information for authentication: UID, PW and DOMAIN.

All application work correctly. After I recived an error from navision (not webservice error but an application error from a codeunit), my authentication is no longer valid.

When application work correctly, on server of sql server, I find the events of my Authentication.
After the error, my authentication becomes NT AUTHORITY\ANONYMOUS LOGON.

Someone can help me understand? ](*,)

PS: During these tests, I have several PC with RTC client that is operating normally.
