  • 1. Spooler Service Not Running. XP Pro SP2 Shared Printer
    We have to continuously start and stop the spooler service in order to print to our shared HP LaserJet 6P. It seemed to start causing problems when we installled SP2 of XP. Any ideas how to keep this service running. We have Cleaned the registry of all printers and reinstalled printers - no luck.
  • 2. internet sharing connection icon
    I have recently installed xp SP2 and among the lastest quirks is that my ics icon is not showing any more in the tasbar on the "client1" computer. It shows fine on the host and another "client2" computer not yet updated with sp2. On the subject "client1" computer the icon was there for a couple of weeks after installing sp2 but now it is gone and I cannot control the connection from "client1". The subject computer does connect to the internet fine. Any Ideas? I have double checked the host computer and on the "client2" I can control the internet connection just fine.
  • 3. Drive Share Problems when using Antivirus Software
    I have three computers on a peer to peer network using Windpws Xp Pro. Every time I try to install Norton Internet Security 2004 on the machine that is storing my data, that machine no longer functions as a network drive. It does not see the other computers and will not allow the other computers to see it. I've also tried McAfee 2005 but that doesn't work either. Has anyone else had this problem?
  • 4. computer name stuck to owner's folder
    HELLO, ALL! I'm trying to take the computer's name off the end of my account folder in C:\Documents and Settings. It's stuck there, like <username>.<computername> I've tried to change the folder name per usual method. No dice. I've taken ownership of that folder and tried. Nope. I've gone into Recovery Console (which was tweaked so that I could access other folders than WINDOWS) and tried to change it. It seemed to work (at least I didn't get an 'access denied' error msg), but when I booted up as per normal, the computer name was back. I've tried logging on in Safe Mode as Administrator, and tried. No joy. It should be mentioned that this unit is the host in a small WLAN, with two wireless-client-laptops connected to it....Also, everywhere I go to view User Accounts (everywhere--Control Panel>User Profiles, or Run>lusrmgr.msc, or in the mmc file, or in Run>control user passwords2), the username is correct, w/out that unasked-for suffix. Anyone help with this?? Thanks in advance. terry.

ping loopback with tcp/ip disabled

Pinging the loopback address tests confirms that TCP/IP is running, correct?

Is there any reason that I can still ping the loopback address even though I 
have disabled TCP/IP? Or is my understanding of what pinging the loopback 
address does wrong?

In article < XXXX@XXXXX.COM >,



The loopback address is internal to the TCP/IP stack and can be used
even with no installed network adapters.

How did you disable TCP/IP?

I disabled TCP/IP through the properties of the connection under the 
networking tab. A lab in the Microsoft 272 book instructed me to disable 
TCP/IP by unchecking the box there, which should keep pinging the loopback 
from working. It did not, and my instructor did not have an answer as to why.

Does unckecking the box not actually disable TCP/IP for the connection?

In article < XXXX@XXXXX.COM >,



Unchecking the box disables TCP/IP on that network connection, and
only on that network connection.  It has no effect on other network
connections, and it has no effect on the loopback address.

The loopback address isn't associated with any network connection.
It's internal to the TCP/IP stack, and TCP/IP runs even when TCP/IP
isn't bound to any network connections.   To demonstrate that, you can
un-install all network adapters, open a command prompt window, and use
the "route print" command to show the TCP/IP route table.  It will
show:
  
   127.0.0.1  255.0.0.0  127.0.0.1  127.0.0.1  1

1.TCP/IP computer can ping world, world can't ping computer

Hi

I'm having a really strange situation going on with one of my Win2000
computers.

As the subject line states, it can ping and access the world (within
and outside of the LAN), however, no other computer can ping it (ie.
ping 192.168.2.3).

This machine is able to browse the web and ping everywhere, but no
other computer can ping it, which means that my XPPro laptop, which
doesn't have the netbui protocol installed, can't access the shares on
the w2k computer.

This machine is connected to a belkin 4 port router (which acts as the
DHCP server). If I set the machine to use a static IP address, it
can't browse the web at all.

I ran winsockfix.exe on it, which kinda resolved the internet access
problem (as long as the computer uses a dynamic IP address).

Also, I have no firewall running.

I already tried replacing the network card (as instructed in other,
similar, threads).

Next stop seems to be a full reinstall of windows 2000 unless someone
comes up with another clever idea.

Thanks in advance!!!!!

Alex

2.Failed TCP/IP Internet Loopback Test Error Code NC315-5W

Hi,

I ran PC Doctor to test the connection on my network adapter (Realtek 
RTL8139/810x Family Fast Ethernet NIC) 

The test failed on the following:

Failed TCP/IP Internal Loopback Test Error Code NC315-5W

Failed Network Communication Test Error Code NC315-1W

If anyone could advise on this it would be much appreciated.

Thanks in advance.

4.std tcp/ip verses hp std tcp/ip printer port

What is the difference between...
[standard tcp/ip]...
and...
[hp standard tcp/ip]...
when setting up a local printer port?
Any insight will be appreciated.
Thanks, Tracey


5.Microsoft TCP/IP V6 and Internet Protocol (TCP/IP) in network settings

Just noticed that I have both Microsoft TCP/IP V6 and Internet Protocol 
(TCP/IP) showing in network settings.

Is this (a) normal, and (b) likely to cause a conflict ? (XP Pro machines)

Should I remove one or the other?

Jeff
