    That's not enough detail for us to be able to help you out.

    Is your SQL Server 2005 instance running on the same machine as your SQL Server 2000? What is your hardware setup? What version of NAV are you running? There are a LOT more things to look at.

    I have uninstalled the SQL 2000. The hardware is same for both.

    Does SQL 32 bit or 64 bit makes any difference??

    so, you have no updatestats and no rebuildindex. do you have create this maint. jobs under 2000 :?:

    How to create a job for rebuildindex or updatestats :?: Search the forum, read online help or, better read the manual on product cd (w1w1isql.pdf)
    Do you make it right, it works too!

    i think you are not the DBA. so ask you db admin if he has created these jobs.

    Also: Which Version of Nav do you use and which Version of SQL2005 you are use. Do you have enabled some traceflags or some indexhints :?:
