Expanding on Jeroen's question ...
Please post the complete output from running the following against *both* dataservers:
================
select @@version
go
sp_version
go
================
I'm wondering if:
a - you're not running the same ASE versions
or
b - you are running the same ASE versions but the problematic dataserver is running with an old version of the installmaster script (eg, the dataserver was upgraded but someone forgot to run the installmaster script).
