hello..
how to do that..
plz plz help me..
Some of the possible causes:
1.If you mess with the 'zone' settings in IE, you can put the web site in the wrong zone. I have seen this happen when someone put the target site in the 'Restricted sites' zone.
2.In Server 2003, there is the new 'Internet Explorer Enhanced Security Configuration', which sometimes causes NTLM to not work, even after the site has been added to the 'trusted sites' group. Try uninstalling this.
3.You can disable NTLM in IIS. Open up IIS manager, go to 'Directory Security', and click 'Edit' under 'Authentication and Access Control'. Make sure that 'Integrated Windows Authentication' is enabled.
4.NTLM could just not be working between the machines. Make sure that you can open up a file share. You might also want to check the event log on the server.
