TCP/IP stops responding.

dhcp renew gives same address and no change in TCP/IP connectivity. A manual address also does not help, only thing that fixes is reboot of osx. I have it isolated to this one macbook. Also noticed that on connected devices list in my router that this one computers MAC address has several listings as New-Host, New-Host2 ect. A non issue for all other devices Any Ideas?

All machines are connected using Wifi with the AE. This morning, the MBA complains that it cannot obtain an IP address via DHCP from the AE. I just get the little wireless icon with the exclamation point, and efforts to 'renew' from System Preferences --> Networking don't help. Other machines working just fine. I have attempted the following troubleshooting efforts, none of which help:
1. I have rebooted (MBA, other Macs, and the MBA) several times.
2. Assigning a manual IP address and DNS settings to the MBA. I have tried to ping other hosts on the network, but Terminal just gives me "you don't have permission" errors. Odd.
3. Turn off Wifi / Turn on Wifi, etc.
I also notice that AFP is working just fine and I can share iTunes libraries, etc. Just TCP/IP stopped working.
Anyone seen this before?

Quicktime Export Error: "An output module stopped responding."

I'm experiencing an odd export error whenever I use any Quicktime codecs:
"After Effects error: An output module stopped responding. The file may be damaged or corrupted. You may need to restart After Effects."
Similarly, Adobe Media Encoder hangs when outputting to Quicktime codecs. Neither program makes any progress at all before the hang occurs. At that point, I have to manually "end task" to exit. Also, it doesn't seem to matter what I try to export. In AME, for example, I can simply try to convert one video format to another and have it hang, so I don't think the problem is due to a problem with the source settings or effects. Also, I'm not attempting any multiprocessing since I don't really have enough RAM for that. Other output modules work, so I'm just exporting image sequences for the time being.
System specs:
Windows 7 64-bit
Intel i7-2600k processor
8 GB RAM
GTX 580 GPU
Software:
Adobe CS6
AE Plugins include Tracode Suite 12 and Optical Flares
Quicktime 7.7.3
Any thoughts on this? I've seen very few references to this error in other places, and not really found a solution that seems to apply to my situation. Thanks in advance for your help.

Thanks for setting me in the right direction. Clicking through to the 25 :: 101 error page (http://myleniumerrors.com/2013/01/06/25-101-4/) led me to a reference about other software, such as remote access software, using the same ports that AE needs for communication with its various processes. In my case, LogMeIn was the culprit. I had no idea that AE even used TCP for these types of operations, so that's very helpful to know.
*EDIT*
That worked temporarily, and now it doesn't work. I ran into a similar effect when I first disabled the Windows Firewall. But of course, as I type this and piddle around, it works again. It SEEMS like if I open AME and click into the output settings and scrub through the video preview, it makes everything work when I go to actually export. That's exactly the type of thing I would say is completely unrelated under normal circumstances, but at the moment all I know is that it is currently working and I don't want to test anything else until I finish the rendering I need to accomplish today. I'll work on it more later and post an update at that time.
Thanks,

Sun Java System Application Server Standard stops responding for no reason

Dear Sun Users and Support.
We ran into an issue that we can't find any cause for. For some reason our Sun Java System Application Server 8.2 Standard stops responding to HTTP calls. Even Admin console can't be invoked. The server by itself appears to be running according to the Windows Services window.
It happens very rarely but once it happens the server needs to be restarted.
There are no logs in the log files.
This happens to multiple Sun Servers at the same time (As if some kind of timer shuts them off).
The servers run on Windows Server 2003.
Any help would be greatly appreciated.
These servers are in the production environment and have expected uptime of 99.9%.
Thank you.

This has happened to us a couple of times and it was caused by Windows running out of TCP/IP connections. Next time it happens do a "netstat -an" to see if you have an extremely large amount of connections in time-wait state.
If you do this is probably the culprit and I'm sorry to say that I don't know of a cure. From what I've heard (objection your honour, hearsay!) this is caused by bugs in Windows TCP/IP stack.
If you require a 99.9% uptime you should perhaps consider switching to Linux or Unix. I know, easier said than done!
Hope this helps,
Gunnar

My itunes opens but stops responding two seconds later....Help?

Recently i got given an ipod and my itunes had been working fine previously. So i loaded my ipod and my two siblings ipods onto the computer and we were downloading music and it was working fine. Later i came back and tried to open itunes and the window opened up but it froze on 'loading itunes store' and stopped responding. I do not have bonjour or asc so its nothing to do with that. Does anyone know how i could fix this? Thanks

The message "this program is trying........" probably came from your secyrity software trying to insert back the LSP.
If you are still having these type of problems after trying the winsock reset and are running any kind of net monitoring software like Bsecure, Net Nanny, AVG Family Safety, Safe Eyes, Covenant Eyes, Norton Online Security etc... I would suggest that you try uninstalling said software and reinstalling iTunes 10.5 to see if that corrects the issue.
Or You may follow article TS4123 steps to identify which software in your system is the culprit and uninstall it. Good Luck!
iTunes 10.5 for Windows: May see performance issues and blank iTunes Store
Last Modified: November 28, 2011
Article: TS4123
Symptoms
You may notice the following symptoms after installing iTunes 10.5 for Windows:
iTunes is slow to respond
Windows is slow to respond
iTunes stops responding when backing up or syncing with an iPhone, iPad, or iPod touch.
Some processes installed by iTunes are using up a lot of resources in the Windows Task Manager.
iTunes Store looks empty and white as shown below:
Products Affected
iTunes Store, iTunes 10 for Windows
Resolution
Look for modifications to Windows by:
Running MSINFO32 by choosing either Start > Run, or using the search box to search for
Once it is open, expand Components and then expand Network.
Click Protocol. The first value should look like this:
However, if you find a value that is more like this, it indicates that there's an LSP (Layered Service Provider) monitoring your computer:
"<LSP Info>" is variable and may specifically mention a software suite, or appear to be a meaningless acronym
Scroll through the list on the right and look for any LSPs that have been installed by third-party software. By default, the Windows OS will have 10 values:
MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
The value above repeated 5 times with additional variables at the end
Note: If you want to know more about which values from this key are part of Windows, please review Microsoft article 811259.
Once you've identified the third-party LSPs, determine which software placed them there. Here is a partial list of LSPs you might run into and the software that may have placed it there:
Product or Manufacturer
LSP Name
Bigfoot Networks
BfLLR over [MSAFD Tcpip [TCP/IPv6]]
ByteMobile, Inc.
BMI over [MSAFD Tcpip [TCP/IP]]
Covenant Eyes
Covenant Eyes Monitoring over [MSAFD Tcpip [TCP/IP]]
PC Tools / Spyware Doctor
PCTOOLS over [MSAFD Tcpip [TCP/IP]]
SafeEyes
Internet Content Filter over [MSAFD Tcpip [TCP/IP]]
SpeedBit Video Accelerator
SBLSP over [MSAFD Tcpip [TCP/IP]]
VMWare
VMCI sockets DGRAM
Once you've identified the third-party software that installed the LSP, you can remove that software. If the software is your security software, see iTunes: Troubleshooting security software issues for additional information.
Note: If unsure on the origin of your LSP, you may try to locate vendor information to determine which software is responsible for the non-default value here.
Reset the WinSock key
If you are unable to identify the software that installed the LSP, you are unable to remove this software because it performs an important function for you, or you've removed this software and the issue persists, you may wish to reset the WinSock key.
To do so, please do the following in an administrator user:
Windows Vista and Windows 7:
Windows XP:
Enter the following command:
netsh winsock reset
Restart the computer and test the issue.
Note: If the issue returns, third-party software may be reinserting the LSP.

These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.

Safari stops responding and gets stuck loading a page

I have the latest version of Safari and it tends to stop responding, won't load a page and has to be forced quit. This only happened when I updated Safari. Can I go back to version2? Firefox works fine. From reading many blogs it seems to be a big problem. Could this knock Safari off the top spot for Mac users.

The following usually works on both Tiger and Leopard:
(First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
208.67.222.222
208.67.220.220
(An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 / )
Click on Apply Now and close the window.
Restart Safari, and repair permissions.
If that didn't do it, then try this as well:
Empty Safari's cache (from the Safari menu), then close Safari.
Go to Home/Library/Safari and delete the following files:
form values
download.plist
Then go to Home/Library/Preferences and delete
com.apple.Safari.plist
Repair permissions (in Disk Utility).
Start up Safari again, and things should have improved.

I am having the same issue. Its says that the server has stopped running. THis has gone on for three days straight. First time it fixed it by powering down the unit, the next time it worked resetting the network settings. Now its happened again and these two options do not work either. What do I do or what could be wrong??

Lync 2013 stops responding when making audio calls

Lync 2013 desktop client in Windows 8.1 connected to Lync Server 2010
From my office workstation (Windows 7, Lync 2010 client, completely different hardware), from inside the firewall, I don't have any problems (IM, audio, conference, video, desktop sharing all work 100%). At home, I haven't been able to make PC calls.
I can see the status of my contacts in Lync, and contact them through IM, but as soon as I try to make an audio call, Lync stops responding. I can, on occasion, connect and can receive audio, but I cannot be heard on the other end.
To place audio calls, I connect to my office workstation through remote desktop - the audio quality is terrible but it works.
I'm testing various configurations using the "Check Call Quality" function under Tools > Audio Device Settings. I can hear a couple of beeps, or even a ring tone, once, but then it crashes again. Waiting 10 to 15 minutes, it still
does not respond.
I am using Lync 2013 because 2010 wasn't available through MS Office HUP. I checked the compatibility list, and I didn't think there would be a conflict between the two versions.
Would downgrading Lync to 2010 help?
I am not exactly a Lync expert, so I may have some of the setup wrong. I'm hoping it's as simple as a server/connection setting that I've missed. I'm using Automatic Configuration under Advanced Connection Settings.
Hardware specs:
DELL XPS 8500
Windows 8.1 64-bit
Realtek High-Definition ALC887 Audio
Creative Labs Sound Blaster Recon3D PCIe Audio Card
NVidia GeForce GTX 660 Graphics Card
According to Windows, all drivers are up to date.
I had a Logitech webcam installed. I disconnected it and restarted the computer, to make sure it wasn't affecting Lync.

Hi,
Did the issue happen only for you or for multiple users?
Did the issue happen when one endpoint is internal and the other is remote or also happen when two endpoint external the company?
If it possible, please try to use another computer login on Lync client 2013 at home.
Please double check if you have configured DNS entry for Lync server Edge A/V service.
Here is a similar case may help you:

Please also double check the Edge external A/V port UDP 3478, TCP 50,000-59,999 and UDP 50,000-59,999 and make sure they are opened.

CRIO disconnects from Ethernet network and stops responding to pings

We are running a cRIO application that periodically disconnects from the Ethernet network even though the VI continues to run on the cRIO.
The application has two parallel loops. One loop reads data from the FPGA and writes it to a RT FIFO. The second loop opens a TCP connection to a remote host, reads data from the RT FIFO, and transmits the data to the remote host. We have instrumented each loop to send messages to the serial port that indicate their status. When the cRIO disconnects, both loops continue to send their status messages to the serial port. The first loop happily continues reading data from the FPGA and writing it into the RT FIFO. The RT FIFO overwrites the oldest data when it fills up to keep it from overflowing. The second loop reports a TCP write timeout (tcp write error 56) around the time that the cRIO disconnects, after which it closes the existing TCP connection and then repeatedly tries to open a new TCP connection (each attempt times out after a 5 second delay).
All that appears normal and usually the connection is automatically restored. Occasionally, however, the cRIO is not able to re-open the TCP connection. Furthermore, the cRIO stops responding to pings from the remote host. On two occasions, the cRIO was finally able to open a new connection after 30-40 minutes. Other than that, the only way we've found out of this dilemma is to reboot the cRIO.
The frequency of the disconnects and the time before they occur doesn't seem connected to whether or not the cRIO is set to run the application at startup or if the application is run via an interactive VI window on the remote computer.
It is possible that the disconnects have something to do with which computer the cRIO is connected to, as the problems seem to happen much more frequently (often within minutes) when the cRIO is sending data to a laptop running Windows XP, but it can run for hours when sending data to a rackmount server running Windows Server 2003. Everything else (the speed and size of data being sent, the ethernet hub and cables, the VI running on the remote computer) is the same.

We're done most of the testing with a 9014 real time controller and a 9104 chassis. However, we've also seen similar behavior with 9014/9103 and 9102/9101 combinations.
The 9014 cRIO normally runs at around 50% CPU usage and less than 40% memory usage when the data is flowing steadily. The RT System Monitor did not indicate a spike in either before the cRIO disconnected.
Measurement and Automation Explorer is not able to connect to the cRIO after it disconnects. We tried pinging the cRIO from a different computer, but that also failed.
After disconnecting, the cRIO sends error messages to the serial port while trying to open a new TCP connection. It reports an error 56 (time-out error) 3 or 4 times (for a total duration of 15 or 20 seconds) and then reports an error 42 (generic error) at least 10 times per second for 18 seconds, and then switches back to 15 seconds of timeouts, and so on. When getting error 42, it ALWAYS gets it for 18 seconds straight. It usually gets error 56 for 15 seconds (3 timeouts) but sometimes for 20 seconds (4 timeouts).
When the cRIO disconnects, it can't be contacted by any computer through the ethernet port, yet the link lights still show that it is connected. If its connected directly, both the green and orange link lights on the cRIO light up, but when it is connected through the 10 Mb hub, only the orange link light lights up, but the hub shows that the cRIO is connected to it. In spite of this, it is still impossible to ping the cRIO in either scenario.
It is possible that, in addition to what computer the cRIO is connected to, the errors could be related to whether the cRIO has a direct connection to a computer or if it is connected through a hub. Today, we have only managed to get errors when the cRIO is directly connected to a laptop (one error after 1.5 minutes, one after 10 minutes, one after 7 minutes, etc.) There were no disconnects when the cRIO was connected to a 10 Mbps hub for more than half an hour.
Do any of those symptoms give you clues about what is happening?
Thanks!

Webserver stops respond randonly on Tools 8.5.05 - Details included ...

Background -
Appserver (ABC)
Webserver (XYZ)
Web and App server are on two separate HP-UX Itanium servers (OS level 11.31).
Both servers have Tux10gR3 and WL1031.
Description -
Webserver randomly stops responding - page hangs. This can happen at a page save, a page refresh/load or when a timeout window is trying to appear. At that time, there is no error log in the webserver PIA_weblogic.log, or domainname.log. While this is happening, I am UNABLE to telnet to that particular webserver port from the appserver.
Eg: FROM the command line of ABC -
$telnet XYZ 8200
Trying...
telnet: Unable to connect to remote host: Connection refused
The issue goes away when the tcp timeout is reached and at that point, login page is displayed for PIA with message - application server is down at this time. A subsequent error log appears in stderr.log and domainlog on webserver
***** JoltSessionPool: Domain //ABC:9200 is Unavailable
java.lang.Throwable
Just FYI, i am able to do this from XYZ all the time, no problem.
$telnet ABC 9200
ADDITIONAL DETAILS -
I have a webserver setup with the same tool set on ABC as well and have not experienced this issue.
Webserver -
ndd -get /dev/tcp tcp_tw_cleanup_interval
60000
ndd -get /dev/tcp tcp_time_wait_interval
60000
ndd -get /dev/tcp tcp_keepalive_detached_interval
120000
While the webserver is in hung state - on the XYZ server -
netstat -an|grep 8100

16.213.0.36.15888 TIME_WAIT
16.213.0.36.24501 TIME_WAIT
Finally, I have reinstalled tools, WL, Tux and PIA on the server. Both machines are running the same OS patch level - in other words PLEASE HELP!! :)

This is getting outside my comfort zone, but that's never stopped me before ;-)

It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort/Wi-Fi menu bar item to turn AirPort/Wi-Fi off, then on again.
2) Try to select your Wi-Fi network from the AirPort/Wi-Fi menu.
3) In the Network panel of System Preferences delete the AirPort/Wi-Fi item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort/Wi-Fi connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.
By the way, you've been misled by poor field labeling on this forum into typing a large part of your message into the field intended for the subject. In the future just type a short summary of your post into that field and type the whole message into the field below that.

Powervault 124T stop responding at a precise hour

Good day to all.
I apologize if my English seems strange but I'm French and not that fluent.
We have a LTO4 powervault 124 T that is behaving strangely : the network stops responding at 3:30 PM GMT and doesn't restart until we power cycle the device. But the backup is working perfectly so there is no issue regarding data backup. The problem is limited to the network.
I tried to change the IP address, toggle between DHCP lease and fixed IP address, no result.
Depending on the time we cycle power, the network stops the same day or the day after, but always at about 3:30 GMT (it can be a few minutes before that time, but it's the time when I receive the alarm from our monitoring system).
I found that if I telnet to the PV address, I get an response from a 'pinon debug terminal' but I don't know the password.
So my questions are :
Can someone here direct me to a possible solution to get the network back to a stable state ? I think about upgrading the FW but I'm surprised when I read that the file I can download from Dell website is 320 Mb big.
How to know the telnet password ? Not sure it can help me troubleshooting the problem but I'm curious to see what this terminal can provide.
Best regards.

Hi again,
I still suspect a faulty USB port.
Your response is still a bit confusing, so just to be sure:
- Did you also try a USB port on the backside of your Mac?
(if your keyboard is usually connected to the frontside, and you normally plug the mouse into the keyboard, it doesn't help to try testing it by plugging it directly in the front port, if this port is faulty, it's still the same port. If this is your situation, definitely try a port on the back)
- When you connected the other (older) mouse and keyboard, they were initially not recognized, but they were after rebooting, so did they function properly after this reboot? Did you connect these on the same port you usually connect your Logitec and keyboard to, or did you try different ports?
- Do you have access to another mouse and or keyboard, which is 100% sure known to work perfectly on another computer? If yes, try this on your mac.
- When you tried the mouse and keyboard on the Macbook Air, did you try it long enough to be 100%sure they work fine? Let's say at least 3-5 times longer then the average freezing intervals on your mac? (If you just tested briefly, you can't be sure.)
- How does it freeze? The pointer just stops moving? or do you see a spinning beachball?
Another thing:
You are posting in the Power Mac forum
you should actually post this in the Mac Pro forum
https://discussions.apple.com/community/desktop_computers/mac_pro
although they look similar, the older Power Mac line were equiped with IBM PPC processor(s), and the newer Mac Pro line features Intel CPU's.
You will likely get more help if you post in the right forum, which is more active.
You can refer to this thread though

I have experienced an issue with iTunes 10.6 in general that has not been resolved by the latest update to 10.6.1. Upon opening the iTunes application, it initially responds but within 15 seconds freezes and is Not Responding. The unresponsiveness lasts up to five full minutes, then the program begins working again. The issue appears to begin as the iTunes Match cloud icon begins animating and checking for updates to my music library.
The same situation also occurs regularly if/when I make changed to a Smart Playlist. The program stops responding for up to five full minutes, then works properly.
Here's some additional information about what I've already attempted in efforts to fix the issue. Does anyone have any suggestions or recommendations for how I might remedy this issue? While it's not crippling my use of the application entirely, it does cause unexpected headaches and delays, and it'd be great to fix it.
I've attempted to resolve the issue by opening a new library and using it temporarily to test, rebuilding the library by starting fresh and importing from my iTunes Library file, and I've also attempted to use iTunes 10.6.1 from a different user account. Finally, I loaded iTunes 10.6.1 onto my external troubleshooting drive which is running the same OS. I've seen the issue persist in each situation. I've also attempted to run iTunes in 32-bit mode as I experienced some success with this fix related to other issues in the past.
I am using an iMac 27" with the quad i7, 16GB, and a 1TB hard drive. All of my music is on iTunes Match and none of it is being stored locally on this machine. My TV and Movies are being stored on an external 2TB drive, as is the iTunes Library file itself.
I would be happy to provide any logs or additional information that could help resolve this problem. I appreciate any assistance and hope to have this resolved at some point. My iMac is typically on 24/7 as it operates as a streaming server for services like StreamToMe, SugarSync, Plex, and other file services. Additionally, iTunes is typically open 24/7 to provide streaming ability to my Apple TVs (1080p versions), though I do have a scheduled task which exits and re-opens iTunes at 4:30AM to prompt syncing of my iOS devices before I head to work (putting the latest unwatched media on them).
I'm sure some of this is unnecessary or extraneous information, but I wanted to be thorough in my explanation and context. Thanks again for your assistance, everyone.

I have resolved my issue with iTunes' unresponsiveness and wanted to post the solution for anyone who might be experiencing similar symptoms. It was really quite simple to fix, I just didn't see it for what it was:
iTunes Match was causing iTunes to stop responding for several minutes at a time, and several times a day.
iTunes Match - which also forces Genius Mode to be on (something that used to cause my iTunes 10.5 to freeze before I turned it off) - would regularly attempt to refresh my database of 21,000 matched songs (none of which were stored on the computer - just in the cloud) and when it would attempt to update or refresh that library, the program would stop responding.
The constant queueing of iTunes Match / Genius also caused iTunes to consume a significant amount of RAM - something that was also causing issues and which I posted about in another discussion.
So, the simple solution was this: Turn iTunes Match off and iTunes quits freezing.
Now, that of course completely eliminates the usefulness of iTunes Match since the music is no longer accessible on this machine in this iTunes Library. So how to restore its usefulness without recreating the problem? Slightly more aggravating, but still working right: I created a separate, fresh new library and named it iTunes Match. When I need music, I hold option when selecting the iTunes app and select my Match Library, which has NOTHING else in it but iTunes Match. When I'm done with the music, I switch back to my 24/7 media streaming library that has my 2TB of TV Shows & Movies (and device sync relationships) in it.
It doesn't seem like iTunes Match causes freezing and RAM ballooning all by itself, it just seems like in a library that's also full of other stuff, it's the final straw that kills the performance. Split the libraries up and things seem to work really well in both.
Not a perfect solution, but until the next release of iTunes, this may be the best bet. I hope this helps someone else out there, but it at least cleared up my issue. Thanks for reading.

HP LaserJet P4015 stopped responding

We have rolled out HP LaserJet P4015 in our entire School District. We have printer communication issue with this printer. It just stopped responding. have tried different versions of Driver, we have updated the firmware, too. Everytime we change the driver it will work and then stopped again. Is there anybody here experiencing the same problem?

I am having the same problem with my P2015dn. Looking at the posts indicate a number of models are having this problem. Mine workvia USB just fine. I can ping the printer, the router shows the printer, the printer shows ready but won't print and if you delete the printer and try and then go back to add printer - it is not found. Judging by the recent flourish of posts, I expect the answer will have something to do with the recent Windows Updates but nothing yet on the HP or Microsoft sites - just a lot of frustration and time wasted on the part of their customers! I hope some one has ideas

TCP/IP stops responding.
