I am getting an error message saying that "lxdnwbgw.exe and lxdncoms.exe are blocked' from my printer driver. It tells me to "allow access." I have Kaspersky antivirus protection. My printer will not print! It is on, plugged in, set as default printer, and WILL scan. . . just won't print.

Please tell about your printer model & brand.

HI,

You can try out these two options one by one to fix it up:

A)
1 Unplug the printer.
2. Uninstall the drivers.
3. Reboot the machine.
4. Go to the lexmark site and download the drivers.
5. Install the new drivers.

B)You will get the "CANNOT RETRIEVE APPLICATION LIST" if your pc blocks the communication from the printer. This can be configured in your personal firewall. This can be Windows Firewall (found in Control Panel, Security Center), Symantec Client Firewall or similar. Depending on the configuration of this firewall you might or might not get pop-up messages from the firewall during installation. These pop-ups will allow you to permanently allow for this incoming communication. But your firewall might be set not to let you decide anything which will typically mean that the calls will be blocked out. This will often be the case if you have a company laptop configured by the company IT dept. You might then have to ask an admin to add exceptions the applications used by Lexmark as the configuration might not be open for you to change.

I think this is the complete list of applications:

Job Status Window Interface: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxdijswx.exe
Lexmark Communications System: C:\WINDOWS\SYSTEM32\lxdicoms.exe
Lexmark Connect Time Executable: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxditime.exe
Lexmark Device Monitor: C:\Program Files\Lexmark 3500-4500 Series\lxdiamon.exe
Lexmark Imaging Studio: C:\Program Files\Lexmark 3500-4500 Series\App4R.exe
Printer Communication System: C:\WINDOWS\SYSTEM32\lxdicfg.exe
Printer Status Window Interface: C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\W32X86\3\lxdipswx.exe

Goodluck,
Please don't forget to rate the solution.

i can install it online if you want contact me

Try downloading the driver from
http://support.lexmark.com/index?segment=SUPPORT&userlocale=EN_US&locale=en&productCode=LEXMARK_X4270&page=product&frompage=null#1
you may have corrupted software.
Let me know if this solves your problem. Thanks.

Go to the manufacture's website that makes your wireless card and download the latest drivers for your device. That should fix the error message every time you start your Dell.

This sounds like a virus to me? you say you are receiving that message, please, is it Windows "Telling" you?, or some program "Telling" you? please clarify? svchost, is not something that should be deleting anything...Both TCIP & netbt are VERY important part of Windows, so I do NOT think, it should be allowed.

Disable firewall to test if it is actually blocking. Windows Firewall should not normally be configured to block printing.

Make a new printer instance, but use a standard TCP/IP port

If that fails, install the driver using the canon setup.exe installer for you unit.

It might be firewall, or in my case I was connected to my office over VPN. VPN connection from my PC blocked printer communication. Disconnected VPN and it started working.

Try this:

Click on START, click on RUN
A small window opens, delete anything that may be typed in it and then type this -

regsvr32 /u c:/windows/system32/spool/drivers/w32x86/3/lxczPSWX.EXE

click OK
