Ok, I did tnsping of XE and got this back:
C:\Users\Charlie>ping XE
Ping request could not find host XE. Please check the name and try again.

So, it seems fine to me. i also checked out tnsnames.ora and saw this:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Charlie-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
Everything looks fine there too. I’m on Vista 64bit and am in the process of downloading 10203vista_w2k8_x86_production-db.zip to see if that helps. I wanted to check before running that patch to make sure I wasn’t going to screw my Oracle 10G Express install up.
