Shaky login on Mac

Normally shaky logins are caused by missing or corrupt edu.mit.kerberos files so always check that first but you might also want to look at the user's e-mail address in AD too.

We had a user who couldn’t log into any bound Mac using his AD account however he could log into a PC. On the Macs, he would get a shaky login box and a cryptic error saying “you can’t log in at this time”.

Checking his AD account I noticed that he didn’t have a secondary SMTP of @corp.ipgnetwork.com. I added the SMTP, waited for replication and then he was able to log in.

Garbled Text in Entourage

Problem: Entourage displays garbled text in all fields- header, folder names and message body.

Fix: Go to /Users/[user name]/Library/Caches and delete the com.microsoft.browserfont.cache file.

Relaunch Entourage and the text should be back to normal.

Entourage not sending mail MSS and MTU packet size problem

We have had a problem in one of our Warsaw offices where their Entourage 2008 clients (connected to Exchange 2007 via OWA) were not able to send mail.

After much trial and error we found that the MSS packet size was set incorrectly. Allowing larger packets resolved the problem.

We set the MSS packet size to 1300 and the internal and external MTU size to 1500

Doing a tcpdump and searching for "MSS" found that the packet size was 1460. However it looks like the tcp packet length to the OWA server is 1400.
