Ms dtc Log File not found. Transactions that are not in an "uncertain" status when you confirm that all resource managers coordinated by ms dtc do not

Run MSDTC-resetlog to create a log file.

My runtime environment:
WinXP Pro SP2;

Solution:
[1]:
Check whether your DTC service (full name: Distributed Transaction Coordinator) can be started normally.

Skip this step. If an error occurs and the task cannot be started properly, run msdtc-resetlog in the Start menu to create

Log File. Restart the machine and check whether IIS can be used normally. If not, continue.

[2]:
Run the following command in CMD:
Cd % windir %/system32/inetsrv

Rundll32 wamreg. dll, CreateIISPackage

Regsvr32 asptxn. dll

After restarting the machine, my problem can be solved perfectly in this step! When this depressing problem occurs, the system directs it once and IIS reinstalls several

Times, BAIDU has some information and finally solved it. I hope it will help you.
