We had a problem last weekend with Postfix not accepting email for a single domain when it was coming from outside our network, while messages from hosts on the local network were accepted and routed with no problems. Messages from outside the network were rejected with a 450 (temporary) code and the error message “Recipient [...]

I ran into a minor difficulty recently on a Linux desktop PC (CentOS 5.4) updated to the recently released OpenOffice.org 3.2, specifically the Go-Oo.org variant that includes some options and tweaks left out of the primary branch. OpenOffice.org 3.2 would start without difficulties, but as soon as I started to type the application would completely [...] I had an interesting problem with a server (Windows 2003 Standard) at a small business (6 users total) the other day – a very long startup time. The server in question is a standalone domain controller/DC as well as a database/application server and file/print server. Terminal Services is installed & configured, but rarely used – [...] Ran into an interesting problem this evening – I was helping someone who was having problems with installing Office 2007 on an XP system with Office 2000 (I believe Professional) installed. The problem was that when the actual installation process started, it would hang up because another installation was running. The standard fix for that is [...] Earlier this week I spent some time troubleshooting a browser-based application that a client is using. The problem cropped up on a PC with a clean install of Windows XP SP3 after assorted system corruption that wasn’t worth the time to repair. Spent some time recently with a laptop that would see networks fine (although IP address acquisition via DHCP seemed slower than I’d expect), but which was unable to resolve names with DNS. This was affecting IE, Firefox, ping, basically anything that used the built-in Winsock calls such as gethostbyname(). NSLookup, on the other hand, worked [...] Quick Fix: have a program named procmon.exe running (copy of notepad.exe) to disable malware temporarily. This should let you run searches & download fixes. This is only temporary while you clean the system. Read this post for more details and please let me know in comments if this does or does not work for you. Update/Fix: The [...] Just ran into this situation after a client uninstalled & reinstalled Office 2007 Pro. When Outlook was opened, it complained twice about being unable to open InfoPath because it wasn’t installed. I found multiple other complaints about this, but no solutions (though some suggested removing and reinstalling Office). A bit of digging with SysInternals’ Process Monitor, [...] There are apparently a variety of things that can cause the winlogon.exe process on Windows PCs to consume all available CPU, but I’ve found few references to this cause – corruption in Offline Files, even when Offline Files is disabled on the PC, on the server and on the domain (via Group Policy). Depending on [...] My antivirus reported an infected file (setpwrcg.exe) this morning, with a file date of 7/19/2004. There were a few things that struck me as odd about this: It didn’t seem like a randomly-generated name, |
