Recently, I was in trouble that I couldn't access the local resourses with my computer like printers,file servers in my office.
I didn't know why.I couldn't ping any local resources but my network card.It's a big problem for me.
At first,I dougted that I'm using NIC and wireless both.then I disabled wireless but it didn't work.I changed the LAN cable but didn't work...
Finally I figured the problem out!
In my Windows computer,I disabled "Deterministic Network Enhancer" in the property of "Local Area Network".
I don't know when This component is installed and enabled and how it works.
But Disabling it works great!!
----------------------------------
I found out more.
I'm using NetScreen Remote for my VPN connection.and that causes my problem.
I guess when NetScreen Remote is installed in the computer,"Deterministic Network Enhancer" is created and enabled.and "Deterministic Network Enhancer" is needed by NetScreen VPN connection.
I found that the Local area subnet and my VPN subnet was OVERLAPPED!!!and that cause the problem.
The only workaround is When I use the local resources,I have to deactivate NetScreen Remote.
In other words,I CANNNOT USE local resourses and VPN connection at the SAME TIME!!
It's a problem.fortunately my company uses another VPN software,Checkpoint.It really works great as VPN client.So I will not be able to use NetScreen VPN software for now.....

Big Brother:HTML Formatting
My company is using monitoring tool called Big Brother.It's right great tool.
we monitor our customer's servers.I will explain how to change html formatting rules of Big Brother.
In some custom scripts,the output contains some html tags like "BR ".
With the default settings of Big Brother,those tags are converted to another strings.As a result,the output in the html format is some kind of wired. So I took some investigation and figured it out.
To use html tags in the output,we need to edit bbdef-server.sh in $BBHOME/etc folder.
Here is the procedure.
On the Big Brother server
cd $BBHOME/etc
vi bbdef-server.sh
Search the description named 'RUNOPTS'
Default value is "CONVHTMLTAGS"
and it needs to change "EMBEDHTML" like below.
#RUNOPTS="CONVHTMLTAGS"
RUNOPTS="EMBEDHTML"
export RUNOPTS
save file and restart BigBrother server.
I refered the following article to find this out.

There's no ADMIN computer right here. I check the microsoft website described but it didn't help me.Finally I figured out that the incorrect printer port caused the error.

Auto Adobe PDF on LENOVO-ADIHELXON
The ports used by those printers are
\\ADMIN\Auto Microsoft Office Document Image Writer

I created new local printer ports and assigned them for 3 printers one by one.After that I deleted 3 wired printer ports.To delete printer ports,
To delete printer ports, Open
Start Menu -> Settings -> Printers and Faxes
and Files menu -> Server Properties
You will see the 'ports' tab and can delete/add printer ports.
