The target name used was cifs/fs. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (ALCAN.BIZ), and the client realm. Please contact your system administrator.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------I have6 servers:1 application server1 profile server1 print and file server1 webserver (linux)1 backup server1 domain controller "i don't have access on this server.

Hi Thomas, The W32Time event 29, 14 and Kerberos event 4 may not related to performance issue. Please help to collect the following information for research. 1. When did the issue start to occur? 2. Is there any new software/hardware installed on clients? 3. MPS Report is helpful. A. Download MPS Reporting Tool (MPSRPT_PFE.EXE) from the following link: (http://www.microsoft.com/downloads/details.aspx?FamilyID=00ad0eac-720f-4441-9ef6-ea9f657b5c2f&DisplayLang=en) Please note: The link may be truncated when you read the E-mail. Be sure to include all text between '(' and ')' when navigating to the download location. B . Right click MPSRPT_PFE.EXE and select Run as Administrator to run this tool, and you will see a Command Window start up. C . Please type Y with the message of <Include the MSINFO32 report? (defaults to Y in 15 seconds)[Y,N]? D . When the tool is done you will see an Explorer Window opening up the %systemroot%\MPSReports\Setup\Reports\cab folder and containing a <Computername>MPSReports.cab file. After collecting, please use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file and then give me the download address. Thanks.
