Ich plane, einen neuen Windows Server 2022 VPS aufzusetzen und den Remote Desktop Services (RDS)-Zugriff einzurichten. Ziel ist es, bis zu zehn Mitarbeitenden einen stabilen, sicheren Zugang zu ihrer Arbeitsumgebung bereitzustellen, damit sie von unterwegs auf unsere firmeneigenen, maßgeschneiderten Business-Anwendungen zugreifen können. Was ich konkret benötige • Installation und Grundkonfiguration von Windows Server 2022 auf dem vorhandenen VPS • Aktivierung und Lizenzierung der Remote Desktop Services • Anlegen der Benutzerkonten (1–10) und Zuweisung der passenden Berechtigungen • Einrichtung unserer individuellen Business-Software innerhalb der RDS-Sitzungen • Sicherheits-Hardening (Gruppenrichtlinien, Firewall-Regeln, MFA-Optione...

I am moving our production DNS from a Windows-based server to a fresh Debian instance running Bind9. The new host needs to be fully authoritative for all current zones, so I will rely on you to extract every record from the Windows server, import them into Bind-compatible zone files, and validate that the answers match bit-for-bit before cut-over. Once the zones are in place, I also want DNSSEC enabled with a properly generated Key Signing Key (KSK) and Zone Signing Key (ZSK) for each zone. Please configure automatic key rollover and publish the DS records I will provide to my registrar. The goal is a seamless switchover with zero client disruption and clean validation on tools like dig +dnssec, dnsviz, and Verisign’s DNSSEC debugger. Deliverables • Debian 12 server with Bind9...

I need a genuine, ISP-issued static IPv4 address (Only I use, not shared) that is geographically located inside Pakistan. The line will front-end a small production web server, so uptime, clean routing, and unthrottled ports 80/443 are essential. I’ll also be running my own mail services behind the same address and will therefore require Socks 5 to be open and fully usable. Here’s what I expect from you: • Provision of the static Pakistani IP with clear documentation of the assignment. • Quick walkthrough (or concise guide) showing how to bind the IP to my on-prem machine (Linux) and verify reachability. Once the IP is reachable externally and the basic connectivity tests for the web server, Socks5 succeed, I’ll consider the job complete.
