Are there any concerns with using a DCOM component from an ASP application
in a shared hosting environment? For instance, stability or performance
issues. The server is a Windows 2003 Web server edition using process
isolation.
Background: A few days ago we got a new hosting client who is using a local
firm's gateway as their payment processor. I ran the install for the
component on a test box and set the permissions to allow access to the
installation folder. But still got an error when I running the provided
test case.
Server object error 'ASP 0178 : 80070005'
Server.CreateObject Access Error
/ccp/ComControlTest.asp, line 13
The call to Server.CreateObject failed while checking permissions.
Access is denied to this object.
Where line 13 was:
Set auth = server.CreateObject("ccp.authorizer")
Finally I checked the system logs and found that I was getting DCOM
errors --"Access denied attempting to launch a DCOM Server using
DefaultLaunchPermssion." This led to a solution of using dcomcnfg to set
the launch permissions for a related object "ccp.settler"
Since no other payment processor or other component we have had to install
for our shared hosting clients has ever shown up in the list displayed by
dcomcnfg, I am concerned that figuring out how to get it running may be only
the initial problem. Is that all we need to do, or is there trouble lurking
ahead?
Thanks,
Mary M. Rafferty
