Basically, I get the exact same problem. I have been beating my head against it for a week now. I have a Dell Latitude C840 running Windows XP with all the latest Service Packs and patches, using Oracle 9i installed. I recently installed JDeveloper 126.96.36.199 and recently went through and tweaked my computer to disable all unnecessary services from running. I don't know which of these two is causing the problem, but TNSPING blows up with the following error:
TNSLSNR.EXE Application Error The Instruction at "0x61915790"
referenced memory at "0x00000578" . The memory cannot be read.
I have tried re-enabling all the services I disabled, but to no avail. Also, I tried getting more information through the Visual Studio debugger and have the call stack and some other information available if necessary. Has anyone else run into this?
Man, this took so long and it's really something I'm just doing with my "spare time", I've been dealing with this for weeks now!
In my case, the problem was a product that I installed to enable my computer to use my cell phone to connect to the internet. The product came with some Verizon software that lets you manage your phone numbers. I installed it and it added two additional network adapters to my Network Connections. I had already removed these because I didn't feel it was worth $0.40 / minute to use the internet. However, there was a service provider called Venturi Personal Client which serves as some sort of network accelleration. This was the true cause of my problem.
Once I actually uninstalled the Venturi Personal Client, my problem went away!!!! Now I can go back to tinkering with Oracle and JDeveloper.
How did I figure this out? I already had a call stack from the Application Error and the last thing on the stack was VLSP.DLL. I did some searches in Google and only found a couple of entries. I looked at the DLL in my Windows Explorer and it was created by a company called Fourelle Systems, which is now Venturi Wireless. When I went to their website and read about their products, it slapped me right between the eyes that the Verizon software aske me something about using an accellerated connection option. I checked and I had already removed the Network Connections that it created, so then I went to my Add/Remove Programs control panel and saw that the Venturi Personal Client was still installed. I was fairly positive that this was only there because of the Verizon software so I removed it, rebooted, and BAM, everything is back to normal!!!
