Hello Chris and others The sun is shining and a little experimenting brought me a little further. The problem seems to be in the data.fs, and probably not in the dns-lookup. I removed the 2.5.0 installation completely and installed 2.4.3 again. It worked fine in an new installation, the authentication popup showed immediately. Then i added the data.fs from the 2.4.1 production server (yes, i did remove the indices) Again, it worked fine, the authentication popup showed immediately. Then i removed 2.4.3 completely. With a fresh 2.5.0 installion and a fresh data.fs it worked fine. Conclusion: nothing wrong with dns Then i added the data.fs. from the 2.4.1 production server, and there the problem was again. A slow popup, 24 seconds to appear. New idea 1: updating via 2.4.3 add old 2.4.1 data.fs to 2.4.3 test server, pack it, and add the result to the 2.5.0 test server

From 2.4.1 to 2.4.3 the size went from 5.5 to 6.1 mb. When i packed it it was again 5.5 mb But when i added the 2.4.3 data.fs to the 2.5.0 installation the problem was there again.

New idea 2: updating via export That is what i am going to do now, but this takes quite an effort. May be somebody has another idea?

Sent by: zope-admin@zo pe.org 13-02-02 04:08 PM Can your machine resolve its own hostname other than localhost? For example, if your machine is named "frobnitz", can "frobnitz" be resolved?

Probably a DNS issue. Can your test machine resolve its own hostname?

Thank you for reacting. Indeed localhost was not in my host file, and i added it, thanks. However, http://127.0.0.1 itself is reacting very fast, less than a second. http://127.0.0.1/manage takes exactly 24 seconds see the authentication popup.

My last mail was a little wrong: my machine is a windows nt 4.0 machine
