Win7 Printer Problems 0x0000007b and 0x00000002.
I've run in to a bit of a problem with printing on our new Windows 7 Pro machines. The machines work perfectly when i first add the printers, which are shared on a 2003 print server, but after about 2-3 days they all of a sudden refuse to print. I've looked in to the problem further and have stumbled across a few error messages. 1. The ports page is completely empty and when i try and add a port, i get the error 0x0000007b. 2. When i delete the printer and try and re add it before rebooting, i then get the error 0x00000002. The only temporary solution is to delete the printers and restart the machine, and re-adding them after the machine has rebooted. This works again for a short random period of time but the error always seems to reappear. It is also worth pointing out that all 10 new win7 pro machines are exhibiting the same issues. They are all in a server2003 domain environment. Cheers

That is because the printer driver installation does not start because of the error. By default high privilege will be needed when you install driver. The clients may need to install the Windows 7 compatible driver on their client computers. Printer driver installation program will prompt that if you would like to install a local printer or a network shard printer. Then select the correct option and finish the installation. If the driver installation program does not help in this, follow the steps below to add a shard printer. 1. Click Start, click Control Panel and double click Devices and Printers.2. Click Add a Printer. 3. Select "Add a local printer". 4. Select "Create a new port". Choose "Local Port" as the type of the port.5. In the box "Enter a port name", type the address as the following format. \\[IP address of the host computer]\[The Share Name of the printer] Then click Next. 6. Follow the instruction to finish the installation. During installing, choose the correct driver in the driver list. Also you can try to add the Windows 7 compatible printer driver to the printer server. You need to install the Windows 7 compatible driver in one of the Windows 7 client, then follow the steps below. 1. Install the driver on one of the Windows 7 clients.2. Launch mmc from Start Search box.3. Click File->Add/Remove Snap-in.4. Add "Print Management". Point to the server in "Specify the printer server". 5. Expand "Printer Management"->"Printer Servers"->"Drivers". 6. Right-click, then click "Add a driver".7. follow the instructions to add the Windows 7 printer driver. After doing so the driver should be added into the server. If the driver is packed, you can directly extract the driver pack and add the driver from Printer Management in the printer server. If the printer driver is not found, the driver should be not designed for enterprise environment. In this case you may need to add the printer from the client side manually.Arthur Xie - MSFT

I have the same exact problem as Martin posted. Arthur, I don't follow your explanation of why this is happening. If the error occurs during driver installation, then it wouldn't print at all. However, the printer/driver installs correctly, and printing works fine, for days in some cases. Then, randomly, the ports disappear, and printing ceases. The "solution" I've seen posted here and elsewhere isn't a solution, but a workaround. It bypasses the server for printing, and instead installs a TCPIP port on the local Windows 7 PC. LOTS of reasons why IT people don't want to do this. For openers, all PCs will need to have driver updates installed manually, instead of letting the server push them out. There's potential for other problems too.It seems that the problem we're having only occurs when the printer is installed on a W2K3 server (W2K8 doesn't seem to have the problem), and Windows 7 clients. This wasn't an issue with Vista.There are a lot of people I found in other forums with the same issue. I can't believe Microsoft isn't being more proactive in finding the REAL SOLUTION to this!

Hi Everyone,My name is John Dickson and I work on the Performance Team specializing in printing support.We may have found a resolution to this issue. Starting in Windows Vista and in Windows 7 we introduced Asynchronus RPC which speeds up communcation to a Windows 2008/2008 R2 Server. Windows Server 2003 doesn't support this new protocol and when Windows 7 trys to communicate using Async RPC, this is most like causing the temporary loss of communcation.The result is the blank driver tab and port tab.The work around is to disable Async RPC by adding the following registry key on the Windows 7/Vista clients: HKLM\Software\Policies\Microsoft\Windows NT\Printers\EnabledProtocols Type: DWORD Data: 6Please let me know if this resolves the issue.

John, thanks so much for this post! This has been a real pesky problem! My printers suddenly went offline yesterday at the end of the day and I just left it. When I arrived this morning, they'd come back online and the jobs in the queue printed. It's been intermittent like this, so the communication issue you describe makes sense. I also read that this seems to be prevalent with W2K3 servers as opposed to W2K8.I made the change to the registry you mentioned. I had to create the Printers key, then add the EnabledProtocols entry. I'll report back with the results after a few days.-Dave MCITP Enterprise Admin/Server AdminMCSE NT, 2000, 2003

John,I'm sorry to say the registry entry did not fix the problem. I have triple-checked my entry in the registry, but the issue persists - intermittent failure to print, and loss of ports and communication with all printers on the affected server(s).Please check if there's possibly a type in the registry location or something like that. I really need to get this one fixed.Thank you,-DaveMCITP Enterprise Admin/Server Admin, MCSE NT, 2000, 2003

Hi Dave,Did you reboot the Windows 7 client after entering the registry key?We have also seen the workaround of restarting the Print Spooler service but this is temporary.If the registry key entry doesn't resolve the issue then I suggest opening up a support case with use to further troubleshoot.Thanks,John

Hi John,Yes I did reboot. If you have anymore info on this issue, please post. I may have to open a case, I've got a dozen Win 7 systems in production now and I can't have this kind of issue from day to day.MCITP Enterprise Admin/Server Admin, MCSE NT, 2000, 2003

Hi John, Thanks for getting back to me regarding this issue. When i add the registry entry, does it have to a be a hexadecimal or decimal? Cheers Martin

Hi Martin,Decimal value of 6.Thanks,John

Thanks, i've made the reg changes to the machines. Due to the random nature of the problem, i wont know the issue is fixed for a couple of days. Although guitarfish wasn't so lucky i'm hoping it works for us. Cheers Martin.

Aloha! Has any progress been made towards solving this issue? I have applied the reg fix suggested and it appears to have reduced the number users whose printer ports have disappeared but there are still a couple who still have the problem. I am seeing more techs mentioning this issue in forums but no permanent solution. Looking forward to correcting this problem and moving to the next. Mahalo, P.

The solution that jdickson posted has been working fine for me. I have about 15 Win 7 clients now, and haven't had any printing issues as long as I make the registry change.MCITP Enterprise Admin/Server Admin, MCSE NT, 2000, 2003

MCITP Enterprise Admin/Server Admin, MCSE NT, 2000, 2003 Aloha, I see in an earlier post that you continued to have problems after the registry change was made. Did you do anything different in addition to the registry change that may have helped? Please note that the registry change has corrected the problem on 18 of the 20 WIN7 computers on my 2003 domain. There are just two stubborn ones that keep having their printer ports disappear. I've confirmed that the registry changes have been made. Thanks for your answer in advance. I’m glad someone has had the same issue and has been able to resolve it. Mahalo, P.

Has anyone come up with a solution that works other than the ones posted here?

Hi Everyone, I was having issues with my printer mapping using GPO login scripts in my W2003r2 Native Domain. JDickson was on the right track. I came across a fix similar to his but with more settings that seem to have solved the problem. Here is the Registry Change that has Fixed all of my 20+ Windows 7 Pro workstations... [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers] [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\PackagePointAndPrint] "PackagePointAndPrintServerList"=dword:00000000 "PackagePointAndPrintOnly"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\PointAndPrint] "Restricted"=dword:00000000 "TrustedServers"=dword:00000000 "InForest"=dword:00000000 I hope this help!
