I just create small sharepoint farm with two servers:

server1.domain.local -> (windows server 2003) it sharepoint WEF

server2.doamin.local-> (windows server 2008) it sharepoint application server with sql db.

I installed k2 blackpoint on server1 with all components(with databases on server2)..but during installation i got only one error with sharepoint web designer (task was incompleated). I cant activate k2 web designer feature over Central Administration runing on server2. But when i run Central Administration under server1 i can activate all k2 features include k2 web designer.

After that when i access my default sharepoint site on port 80 over server2 i cant view any list and i got error with view any webparts. But when i access my default sharepoint site over server1 everything works fine (i can use k2 web designer tool normaly). I installed on server2 K2 Clients Components and now i just view my default pages over server2 normaly, without errors.

But when i want to use K2 web designer over server2 on custom list its look like that k2 web designer want started but sharepoint site returned Unexpected Error.

In Alternative Access Maping i have both path of server1 and server2 set correctly.

Only differencies between server1 and server2 is IIS...Manualy i copyed all sourcode dll from assembly on server1 to server2..it doesnt help me..

Have anybody any idea how resolve this error? Thanks
