Hello, I've a setup: Zope 2.5.0 with INSTANCE_HOME Windows 2000 server Oracle 8i 8.1.7 client ZOracleDA (dcoracle2) 1.1 When I run Zope from command line, everything is fine. When it is run as a service, the product doesn't give any error. But when you try to open a ZOracleDA connection, it raises an error in connect.py. The same DB connection works flawlessly when Zope is started using the batch file. I've - cross checked the parameters in the registry and batch file. Same. - Recompiled ZOracleDA binary - Moved ZOracleDA from INSTANCE_HOME/Products to lib/python/Products and back Our sysadmin would like to run Zope as a service. I'm at my wits end with this now! Any hints/suggestions will be appreciated. Thanks in advance - vsbabu
