Common Enterprise Pain Points

Many issues look like a single fault, but often involve accounts, permissions, DNS, network, firewall, servers, clients, and business processes. Clarify the pain point first before choosing the handling direction.

6

02

Impact of These Issues

Business Impact

  • Employees cannot log in, access systems, print, or use business systems normally
  • Repeated failures increase internal support time
  • Unclear permissions may cause accidental deletion, unauthorized access, or difficult handover
  • When business systems are interrupted, fast recovery and rollback paths are lacking

Impact on Future Development

  • New systems, VDI, branch networks, or backup projects become harder to move forward
  • Historical configurations without documentation increase maintenance and handover costs
  • Unclear security boundaries make changes increasingly complex and risky
  • Migration, expansion, and remediation lack reliable references
