HTTP-Error: Lotus Notes Exception: Note item not found

Hello!

Yesterday we have our Notes-Server migrated from Domino 5 to Domino 6.5. Now we have a Problem with one Database at the Web-Access.

I can open the Database from Web. I can see the View correctly and can also navigate through the View. Everytime when i will open a attachement with f.e. the following link: http://yk085000s110/bank/Arbeitsa.nsf/WEBNST/3AB5CFE0008CCCC141256B1E00538F2D/$file/101_b.pdf

ther will be shown in the Browser a Error Message: Error 500 - HTTP Web Server: Lotus Notes Exception - Note item not found.

Can anybody help me? I can’t find the Problem…

Thanx

Michael
