Has andbody run into this problem on Windows? The "Windows People" are installing a new Windows Server 2016, and it seems some 32bit applications can't connect to the network in some cases. (with host not found errors) The same setup works on any "other" Windows clients like Windows 7 and 10 and Server 2008 we have around.

sqlplus (and 32bit programs that use the 32bit Oracle client) are also affected, so maybe someone here has seen it and has found the solution? (Perl CPAN and 32 bit wget have similar problems, so I'm pretty sure it's primarily a Windows bug of misconfiguration, but any ideas would be appreciated)

64 Bit client works....
C:\Program Files\Oracle\Client_11_64>sqlplus user/pass@db

OK, right after I posted a got another lead:

With IPs in the tnsnames.ora it works. With hostnames in tnsnames.ora it doesn't work. (same with wget. With IP it works, with hostname not)

So I will give THAT ticket to the "Windows People" Wink

add entry to local "hosts" file.

It's on my list of possible workarounds. But since there are now eight other different applications in total that exhibit the problem, the ball seems to be firmly in the Windows admins court for now. Laughing

Just FYI: The third tier of Microsoft finally found out that there was something botched with the install media of the OS that caused all kind of "weirdness". On a fresh install everything looks fine.
