Unable to load DLL 'CCITCP.DLL': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

We have a webservice that we are creating in order to access our Legacy Cobol files.  When we run the webservice locally on the dev PC we can read our files successfully thru our fileshareService.  However when we publish the webservice on the server we get the error "Unable to load DLL 'CCITCP.DLL': The specified module could not be found. (Exception from HRESULT: 0x8007007E)". 

We are on ED 2.3 update 2

thanks
