Input File Repository Server not available for Crystal Reports client

Hello,

I Have a BO XI R2 Servicepack 4 clustered environment (2 nodes). Publishing Crystal Reports from Crystal Reports client went well until recently. With not probable cause it doesn't work anymore. Whereas importing reports from within the CMS still works without any problem. To be more exactly: When I try to publish from the Crystal reports client (with the same user, that still works in the CMS) I can see the CMS folder structure! but when i try to publish to a certain folder i get the message: Input File Repository not available. I wonder what this could be because I can see the CMS folder structure from the Crystal client (so apparantly the login to the cms went well). And from there on the publication process to the ifrs should!? be handled the same by the cms. But apparantly it isn't.

I really would like to get this solved. Because it is much harder to publish from within the CMS (report settings have to be set beforehand)

Wat can be the cause? Can anybody please help me?

Kind Regards,

Erik
