After spark login, the system disappears and the problem is resolved.

This problem has plagued me for two days. I uninstalled the dr. COM Client (we had to install this client on the Internet to log on to the server, and later we had to enter the user name and password on the webpage). The problem was solved. Problem: After openfire and spark are installed on the lab machine desktop, everything runs normally. But after you go back to the bedroom and complete the same installation and configuration on the notebook, spark disappears after login.

At first, I thought it was caused by system incompatibility. Because the XP versions on the two machines are different, I started to toss my fragile notebook and reload the system n times, during this period, I purchased an XP product. After installing the system, I did not install any software. I installed openfire and spark directly and ran OK. However, with the installation of necessary software, the same problem occurred, locate the error log, and find the "problematic frame: # C [tcpipdog0.dll + 0x6725]" on the Internet. The tcpipdog0.dll file is installed with dr. com. uninstall com to solve the problem.
