Hi I am usinng exchange 2007 till yesterday its working fine but from tomorrow morning when connect outlook than it connect to mail box server properly but my CAS server is frequenlty asking for password, i am using two CAS server they are working In NLB.......but one of them is asking for password frequently... any one can help me to short out this problem

Hi , If the machine is a member of the domain, then set the authentication to NTLM and you will not be prompted. You also need to ensure that integrated authentication is enabled on the virtual directory. However if you cannot use NTLM or the machine is not a member of the domain then you will have to live with the prompt because Outlook needs to authenticate with something. I hope this will help you.

What is profile you have created, if it is MAPI then why it is asking password for CAS server. Please check outlook connector status in taskbar at PC and see is any error. Also scan event log on CAS server and post here. also check DC connectivyt from server.Anil

outlook connection is working fine there is no issue at there but cas server is keeping for password??

i have just reset my IIS on CAS it will working fine now thankx

Hi , I think your virtual server was not working properly at that time thats why it did not get the NTLM and when you restarted it worked. Regards. Shafaquat Ali.M.C.I.T.P Exchange 2007/2010, M.C.I.T.P Windows Server 2008, M.C.T.S OCS Server 2007 R2, Phone: +923008210320
