have a proxy server in our office on Windows NT server,
which is a PDC. I want to configure a proxy array
in my office for which I have to install another proxy
server. I would like to know which machine i.e. the
operating system should be selected. Also which PDC
and BDC should be installed? Kindly give the details.
Windows NT is ideal for installing a proxy server.
A PDC (Primary Domain Controller) is a system which
has all the security information stored in it. You
must and should have only one PDC at a time in a domain.
A BDC (Backup Domain Controller) is a system, which
acts as a backup for a PDC. All the information from
the PDC is regularly updated into a BDC. So that whenever
there is a PDC crash, one of the BDC can be upgraded
Since you already have a PDC and proxy server installed
on it, you should install proxy server on the BDC.
On connecting our computers to the network, usually
one or two computers display 'illegal operations'
error or they just hang. Also, the proxy server is
not functioning properly resulting in fluctuating
Internet speed. Kindly help solve the problem.
Let's address your first query.
You may get the error message illegal operation
due to various reasons like faulty memory, bad motherboard
or IRQ Conflicts. These error messages also flash
when the evaluation version for any software that
you use expires. In that case, you need to uninstall
that particular software and then download the latest
You may also get an illegal operation error when you
do not clear your cache, History Folder and Temporary
Internet Files or due to corrupted disk cache. To
clear the cache, go to Options - Network Preferences
- Cache and click on the button Clear disk cache now.
Clearing the disk cache directory manually (deleting
all contents) might also be necessary. An illegal
operation error can also occur when two programs try
to use the same resources on your computer at the
same time; a regularly occurring illegal operation
error is a good indication that your software was
incorrectly installed, and may need to be reinstalled.
A sporadic error is harder to track down. This kind
of problem is usually caused by a hardware problem,
but not always. Faulty memory, bad motherboard, and
IRQ conflicts are almost always at fault.
When you encounter this error, click on Details and
provide us the exact error message you are getting
so that we can get back to you with an appropriate

frequently occur and their resolution are given step-by-step

I want to setup a two-way trust between Windows NT
domain and Windows 2000 Advance Server domain. The
Windows 2000 domain trusts the NT domain but when
I try the reverse (to setup the trust for NT domain
trusting Windows 2000 domain), I get a message "domain
can not be found'' or "you do not have logon
access to domain."
I am using Administrator account with the same password
on both domains and am working in mix mode on the
Active directory. I have 2 network cards, which are
using Compaq teaming, so there is only one IP address
assigned. I also have a network card for a private
cluster communication using a different subnet IP
address. Can you suggest any ideas as to why the two-way
trust is not working?
To ensure the two configurations communicate with
each other properly, you need to set up a two-way
trust relationship between the Windows NT and the
Windows 2000 servers.
For this, you need to log into the Windows NT Primary
Domain Controller (PDC) as the domain administrator
and open the User Manager for Domains. Select the
Trust Relationships option on the Policies menu and
create a two-way trust to the Windows 2000 PDC. First
select the Trusting Windows domain, and then add the
Trusted Windows 2000 domain. Finally, log on to the
Windows 2000 DC as the domain administrator and open
the Active Directory Domains and Trusts tool located
under Administrative Tools. You create two-way trust
relationships to the Windows NT PDC for all domains
in the enterprise by adding the Trusting Windows NT
domain first, then adding the Trusted Windows NT domain.
You can now set up trust relationships between the
Windows 2000 server and Windows NT.

I bought a networking kit and got my 2 computers networked.
I can't figure out how to use the printer sharing.
My wife's printer doesn't work and I don't know how
to work on her computer and print it on my printer.
Also, can I print something that's on her files from
my computer and printer, or copy something from her
computer to mine? If so, how do I do all this?
To use the Printer sharing and files on other system
you should install and configure the following in
both the systems that you wish to connect:
Client for Microsoft Networks
File and Printer Sharing for Microsoft Networks
NetBEUI and TCP/IP protocols installed on both
To add these components, use the appropriate method:
Client for Microsoft Networks
Click Start - Setting - Control Panel go to Networks.
On the Configuration tab, click Add.
Select Client, and then click Add.
In the manufacturer's box, click Microsoft. Select
Client for Microsoft Networks, click OK.
File and Printer Sharing
Click Start - Setting - Control Panel, and then
Select Add - Service - Microsoft.
In the Network Services box, click File and printer
sharing for Microsoft Networks and then click

I want to setup a 5 - 10 machine peer- to-peer network.
All machines have either Windows 98 SE or Windows
2000 Professional installed. I have a 16 - port hub,
and a cable connection from Spectranet that I would
use for all computers on the network to access the
In a peer-to-peer network, it is realistic to choose
a 10BaseT cabling scheme using twisted pair cabling
and a hub, or "10Base2" cabling used coax
cable, T-pieces and terminators. Once you have decided
on the type of cabling you are going to use, you then
select which network
card you are going to install. This is because, without
a network card, your PC will not be able to connect
to the network and access or share information with
other computers. Please visit the following links
for detailed information on setting up peer-to-peer
network using a hub:
On Windows 2000/ME (client machine), I am unable to
connect to my RAS server using dialup. It gives error
619, port was disconnected. But I am able to connect
to the Internet thereby ruling out problem of modem
connectivity. I am able to connect to RAS server on
Windows 95/98 but not on Windows 2000/ME (client machine).
This issue occurs because the account you were logged
on with at the time you joined the domain did not
have administrator privileges on the Windows 2000
domain. Because of this, services that could easily
compromise network security, such as RRAS, deny clients
the ability to obtain access to the domain.
I would suggest that you do the following to solve
Firstly you must register the RRAS server in Active
Directory using an account that has domain administrator
permissions. To do so follow the steps below:
Add the RRAS Computer to the appropriate group:
Log on your Windows 2000-based computer with an
account that has administrator privileges for
Windows 2000 domain.
Note: This method may be used with Windows NT/2000-based
based RRAS or RAS servers.
Launch the Active Directory Users and Computers
MMC snap-in and then double-click your domain
Double-click the Users folder, and then double-click
the RAS and IAS Servers security group.
Select the Members tab.
Add the RRAS server to this group.
Use the Netsh.exe Utility
Note: The Netsh.exe methods can only be used
if the RRAS server is Windows 2000-based.
Use either of the following methods with the Netsh.exe
Method 1: Log on the RRAS computer using an
account that has domain administrator privileges,
type Netsh. RAS add registered server at a command
prompt, and then press enter.
Method 2: To run a command with administrator
privileges without being logged in as an administrator:
At a command prompt on the RRAS computer, type run
as /user:domain name\administrator name "cmd",
where domain name is the appropriate domain name,
and administrator name is the appropriate administrator
name. You are then prompted to enter a password for
this account. If this computer is able to connect
to the domain controller and verify the credentials,
a command prompt opens with the following information
in the title bar: cmd (running as domain name\administrator
At a command prompt, type Netsh. RAS adds registered
server at a command prompt, and then press enter.
