Moved to Corporate User Assistance for faster handling.
On second thoughts I moved this to Network Security Platform for faster support.
The Attack ID '0x41703b00' is for 'LDAP: Microsoft Active Directory Heap Overflow'
If you view the alerts within the RTTA do you get any more information?
What NSM version software are you running?
What SigSet version are you using?
What model of sensor and software version are you using?
When was the last time you tuned your database?
Were you able to resolve your issue?
I see there was a problem with SigSet 126.96.36.199 that caused it to generate false positives for this alert, details are available on the support site;
Network Security Platform (NSP) Signature Set 188.8.131.52 may generate false positives for certain attack signatures
