PCAnywhere 中有个 ThinHost 的功能还是很不错~ ，不用安装SMA~ 直接推送一个 精简的远程控制代理来处理一些突发问题，
但如果用户管理员的电脑只是安装 pcAnywhere Quick Connect ，默认是无法使用 ThinHost 这个功能的，
需要安装 完整的 PCAnywhere 客户端 ，或者 从NS服务器上 复制一些 需要的文件。

You have two options:
1. Remove the thin host and reinstall the pcAnywhere plug in
- Open the Windows Services and stop 'pcanywhere thin host'
- Access the install files for pcAnywhere at \\<server>\nscap\bin\win32\x86\pcaagent
- Run 'pcaclientinstallmanager /uall' from the share above or copy the files locally and run the executable.
- Reboot the machine.
- Run 'pcaclientinstallmanager /iall' to reinstall
- Update the client configuration
2. Manually copy the missing files to the computer from the SMP server (after the pcAnywhere Quick Connect component has been installed to the computer):
From the SMP server under C:\Program Files\Symantec\pcAnywhere, copy the following files
KillHost.exe
RemStart.exe
SeeBuilder.exe
SymZip.dll
ThinAWCP.dll
ThinCrypshim.dll
ThinCrypto.dll
thinhost.tar.gz
thinhost_mac.tar.gz
ThinHostLauncher.exe
ThinHostProbedll.dll
thinprobe.exe
ThinRes.dll
ThinSet.exe
THook32.dll
THost.exe
THostXProbe.dll
