Content repository ZS does not exist

Hi

i am connecting extertnal server using SAP archive link interface HTTP 4.5

i have done following conifguration:

1) Transaction Code :OACO : Define Content Repository

Create your content repository : ZS ( XYZ is your content repository)

Document Area : Archive link

Storage type :HTTP content Server

Version no. : 0045

HTTP Server :Enter IP address of content server

Port No : 9025

HTTP Script :Default.aspx

2) Transaction Code :OACT : Define Content Category

Create your content category : ZABC

Document Area : Archive link

Content Rep : ZS

Now when i click on test connection in OACo tcode.. it gives me error Content repository ZS does not exist

even i can see in my HTTP API , i have returned parameters contRep= 'FD'

but still i am getting same error.

when i see in SMICM ICM_DEv trace ... it returns HTTP 200 Ok status code .... but in OAC0 screen test connection says ZS does not exist

please suggest some solution

Thanks
