Hi all, I've got a very strange issue. We use WSS3.0 installed in non-AD mode. It keeps a single site collection running on application with NTLM authentication provider. While all users get regular logon dialog behavior (provide their password only once during first access), all Thailand users get login dialog very often. We don't success to figure out what the dialog appearance depends on. I mean they can work for a few minutes without any problem, and suddenly they start getting this dialog on each request (click). Moreover, the appearing logon dialog already contains their credentials (username and password) inside. More-moreover, it doesn't matter if they click Ok or Cancel on this dialog, the requests always success. Is there any ideas what can cause such behavior? Thanks. Thanks, Michael

Hi Misha, Check your Site running on internet zone or trusted zone. if it's not running on trusted zone some times it'a ask us to provide credentials on regular basis. For your reference i am providing the steps here: Go to IE Click Tools from menu bar----->Internet options---->Security--->click Trusted sites---->add your site url in tha tzone. click OK. Thanks, Nivas

Thanks all for replies! Lambert, My WSS is installed on Win2k3 server, which is not domain and not joined into any domain. It just uses local user accounts. Users authenticate with NTLM, rather than Kerberos, so I don't have any problem with login dialog appearing once, on the first access. Generally, everything works ok for all users (EU, USA, UK) excepting the ones from Thailand. I thought it's a client side issue, but ALL users from Thailand getting the same problem :( Nivas, The WSS domain is added to the trusted sites list in IE. I set HTTP sniffer on one of the Thailand users machine and saw that he never fails on the main request retrieving HTML, and all 401 responds come for subsequent images/CSS requests, while these requests indeed contain NTLM authentication ticket in the header. Is there any chance it refers to some file system permissions on the WSS server? Thanks.Thanks, Michael
