PFDavAdmin and Exchange Mixed Environments

I've had a large number of problems with mixed 5.5/200x environments and public folder replication.  It seems sometimes that the public folder permissions do not synch correctly.  This tool has helped me enormously.  You can find a link to it here:

DNSer Configuration

I use DNSer to update my Dynamic IP address as I found that the modified firmware in my Linux based LinkSys router wasn't updating it regularly enough.  Here's my example DNSerSvc.ini file:

[Source]
Interval=600
URL=http://checkip.dyndns.org
User=test
Pass=test
Proxy=
ProxyPort=
Prefix=IP Address:
Count=1
Log=1

[Srv1]
URL=http://members.dyndns.org/nic/update?hostname=yourhostname.homedns.org&system=dyndns&myip=%s
User=yourusername
Pass=yourpasswordProxy=
ProxyPort=
MinInterval=600
MaxInterval=2160000
StatusOK=good
StatusOK1=nochg
StatusOK2=abuse

Replace the bits in red to get it working for you.

I use this with http://www.dyndns.org and DNSer can be found here:

LCID or Codepage?

I was demoing how to change the displayname format in Windows 2003 AD when the question came up about what the code 0x409 meant.  It's the LCID for US English.  Here's a list of LCID numbers used in Windows XP - It shouldn't be that different in Windows Server 2003.

How to set Linux Proxy Settings

Many programs support the use of an environment variable, so setting this in '/.profile' for example can make programs work:
export http_proxy=http://192.168.0.2:8080

KDE has an option in the Control Centre to configure it:
Control Centre > Internet & Network > Proxy

Gnome uses the gconftool-2 command line for proxy settings:
gconftool-2 -s /system/http_proxy/use_http_proxy -t bool true
gconftool-2 -s /system/http_proxy/host -t string "192.168.0.2"
gconftool-2 -s /system/http_proxy/port -t int 8080
